It’s not just the resolution, stupid

For a thorough assessment of my research up until this moment, please see the blog dated 8th February entitled Time and Resolution: Experiments in High Definition Image Making, which outlines my work and current findings.

Since showing some of my high resolution works in Xi’an in China this June/July, I’ve come to realise something about the other factors that make resolution work as an artistic function.

This insight has come about because my Chinese audience expressly communicated that they liked the work that I was showing them because it chimed with them and their values. There was an outbreak of discussion around the relationship between form and content during the symposium that accompanied the exhibition where my work was shown in installation form. I also showed work in my presentation as did Peter Richardson from Dundee University in his choice of Portraits of the Smerset Carnivals. Our Chinese hosts argued strongly that much of the Western art that had been brought to China gave priority to the exploration of technical as opposed to artistic values in the majority of the work. Given Western funding priorities towards science rather than art, this was insightful of the Chinese participants to ferret this out.

This was not the case in their response to my own work however. My work had an amazing reception – I’ve been asked to some right back and teach and give workshops and show more work -perhaps I’m part Chinese or there’s something in me that chimes with their value system – and here I’m mindful that I’m talking about the most recent iteration of the concerns of about a quarter of the population of the planet – and this in itself makes me very happy. I don’t really care if our little western backwater doesn’t respond as well (although in some situations it does – it really does). It’s quite amazing that something that I’m doing chimes with the Chinese mind, though and it’s this that has set me enquiring into what it is that works.

The character of the response was that they really got what I was saying (given that the artist hardly ever knows the true direction of the impact of their work) in fact we set ourselves our obsessive compulsive tasks and then the audience receives the work in a completely different way anyway. C’est la vie.

There was in fact a recognition that there is a technical background to what I do – after all the work is made at 4k and then displayed as high as I can display in terms of resolution, and it’s been my conviction through observation of the audience response that people engage for longer periods with the work the higher the detail it carries. But – but. There’s something about what I’m choosing to create an image of and the way that I’m presenting it to the audience that is engaging people i n a powerful way. Again, I’m trying to be pure about what I’m writing here because I’m totally aware that on some levels what I’m writing could be seen to be self-promotional – that’s not the case I’m trying to decipher the cause of the response.

When TV seeks to show off its higher resolutions it shows nature and landscape footage. It’s impactful for a moment – you know the shots, the polar bear mother skids across the thin ice in case she breaks it followed by her cub who’s playfully batting her legs; or the wilderbeast shot from a balloon race across the veldt in their migratory pattens avoiding lions who are there for the kill; we see a tree canopy before the shot glides into the distance as the earth drops away from us as we soar over the mighty waterfall. Etc.

And I mean ‘etc’ because shots like these have a function which is a part of the form of the trail or longer documentary that they reside in. What I’m really saying here is that yes, these shots exploit the capacities of the higher resolution cameras and displays but that’s all they’re really intended to do; punctuate the form they reside in and the kind of thinking they derive from is the commodification of form – that its impactful-ness is utilised in loss of personal determination in relation to the emotionalism of the form. What I’m talking about here is something Brecht recognised - that the audience is simply ustilied by the artist in a group act that is all about its manipulation – it ebbs and flows in its sympathies according to the determination of the authors.

It is true that most all authors want their audience with them – but in some case – most cases – there’s an unscrupulous attitude about the audiences self-determination. Should it for instance divide its allegiance from the authors purpose, then author in terms of the sale of the work as a commodity would see it as a failure. Hollywood takes no hostages, it wants a ‘satisfied’ audience. And satisfaction is about a set of values that are learnable by any student who studies in the standard educational model to manipulate the audience. It is a loop that cirtcles around and around.

Craft oriented education wants complete control form the student of the form, contextual studies wants a critique – thye are essentially at loggerheads in their intent which is a real pedagogical problem.

The artist however wants above all to challenge the audience and not simply lead them like a lamb to slaughter at the altar of quiescence in terms of the value system that most media is utilised to reproduce.

In my work I have absolutely no interest in commodifying the form because in so doing it lessens the potency of the act of engaging in research in resolution – my work is about revealing the potency of the aesthetics of the form – and these aesthetics directly derive from the technical base of the form. This is also a ‘take-no-hostages’ approach – but it is in the interest, in the end, of the self-determination of the audience. I want the audience to consciously be able to disengage at any point with the work and given that element of the contract between artist and audience, then the audience can sample the act of engagement free from my manipulation of them.

So what works in terms of aesthetics when you’re involved in a guided tour through resolution (which is what my artwork is about)?

I am trying to offer complete engagement on a par with anything that Hollywood – or for that matter any contemporary art values that are perpetrated by aestheticians or art dealers can offer (both of whom are quite happy in each-others company though course they really should be deadly enemies if things were not currently upside down and inside out).

In the work I am enthusiastic about presenting an image – like Whistler vs Ruskin, I argue that 30 years behind a camera renders me experienced. I am a very practised cinematographer and have framed a thousand shots for a thousand different reasons for a thousand different directors, having committed myself to learning just what they desire and just what their aesthetic is (that’s something that happens between all directors and directors of cinematography – at least since the notion of the auteur director came into vogue).

Through having been in very many situations where it has been my sole job to ‘find’ a frame, with special regard to what my director might like, I’ve learned my trade. But at the same time my own imagination has soared in very many directions whilst accomplishing what particular directors want. Set me free with a camera and the black space around the light area that is the framed image is the most potent thing that can happen to me.

I am a camera.

So – as an old tutor once said to me, put thirty photographers in a white room with a window and you’ll get thirty different photographs – one of which will be close to brilliant – and that is the image I seek to find in all situations – that’s what cinematographers do (besides all the other stuff like invigorating the crew, judging exposure, imagining the look and the treatment and carrying the entire production through from inception to display).

Ok – enough description of what the cinematographers eye and mind are engaged in and why I and others like me can imagine what to do with the world and how to imagine it into being.

But there are other factors – the factor of the choosing of the image in the first place. Take for instance my Portraits of the Somerset Carnivals that particularly caught the Chinese eye and mind. Shot at night with the illumination coming from the carnival floats themselves (a cinematography problem in itself – judging exposure of the self-illuminating object), the idea was to shoot a portrait of a float as it stopped in its procession and then display it at 20 feet by 10 feet so that it was the same size as the original and then have it displayed in a different context from its capture. Xi’an in China is about as different as you can get from the original carnival location in Somerset.

So I gather at 4k and re-present at 2k (or 1K if there’s no budget) and this act alone allows the audience to peruse the work without the distraction of the petrol fumes and loud disparate sound sources that are coming at them in the original situation.

Then there’s the sound which accompanies the work – I would have asked a composer to create a soundtrack that also removed the original from its environment to an equivalent amount but to hand (or rather in mind for some twenty years) was Brian Eno and Robert Fripps ‘No Pussy Footing’ – the Heavenly Music corporation piece. I can’t describe it here other than to say: it’s abstract; it’s comprised of backwards and slowed down guitars and their overlays and echos. It was a perfect accompaniment. Sound is as important as resolution of image and does the extra work of disassociating the image from it’s prior relationships and ten conferring new resonances – these choices make the artwork (with other choices like how to display etc.

When shown in a 15th century barn in Somerset the piece has been described using the following words:

Classical statuary
Marionettes
Paper cut outs
Wedding cakes/Icing
Cloud formations
Science fiction film
Wild West
Mexican Day of the Dead
Mountains & Snow

The qualities the work brought to mind

Crystalline
Archaic
Glamour
Ghostly
Smoky
Feathery
Wild !
Painterly
Abstract
Ethereal
Baroque

This was followed by the following description:

‘What was exhilarating was the contrast between the slow meditative movement and image size of the floats passing by with the hectic activity on the film surface as lights went on /off / in /out smeared and melding, twisted and turned – was very visually exciting and allowed the eye to roam and alight on the new forms created within the detailed density of the frame. There is a monumental quality to the film – I don’t know if this comes from this contrast between the large size of the floats in frame and the total eyeful (!) one gets in looking at their details.

The almost harsh brightness of the float lighting against night is not something one sees outside of city so it was strange to see this in a barn with barn and an ancient one to boot !’

This refers to the location of display – a 15th century Somerset Barn.

In Xi’an the audience were equally enthusiastic. The translator did their best but I could see from the sparkle in the audiences eyes as they crowded around me to ask questions afterwards that they too found something similar. They talked of the powerful symbolising influence of the work – but with no particular symbol in mind. I think they meant by this that they were moved – and I do not mean emotionally, I mean more that they identified with the commitment of the act of engagement without usual western demands of having to give up their autonomy.

The idea of being moved without a definite reason is exciting because it intimates a spiritual movement and not emotional movement.

But it wasn’t just the Chinese that responded in these terms, the Swiss, the Germans, the Canadians, the Austrians and Finish all responded in a positive way. There was something in this screening which went beyond simple national boundaries and the work ‘spoke’ across these boundaries in n interesting way. The director of ETH, the institution where Einstein studied, talked of powerful ‘mesmeric symbolism’. Mesmeric Symbolism – this isn’t trance state, where one leaves what one was to enter another space, rather this is a state where you come to with a degree of transcendent emotion – all these words are wrong of course because emotion is not useful in the higher states – emotion is a lower state in some ways. Being uplifted is a general way to tal about this state.

Actually at this even the effect of the work was so powerful I received three distinct formal offers to bring the work and talk about how high resolution images was developing new aesthetics. The Swiss, the Canadians and the Chinese all responded in this way.

The work certainly mesmerises – but in the way that a hypnotist hypnotises – that is you are aware of everything and will do nothing against your will.

The eye is delighted by the surface texture of the image – there is much going on as the report above communicates about colour and detail.

I’ll stop now because it will take time to disentangle what is exactly going on. Watch this space for further thoughts about the extra characteristics required to make a successful artwork in High Resolution.

Exploring Digital Beijing

For a thorough assessment of my research up until this moment, please see the blog dated 8th February entitled Time and Resolution: Experiments in High Definition Image Making, which outlines my work and current findings.

If you’ve been to Beijing you’ll know that the West’s framing of the grand digital project is just that – a Western framing of the overall digital project that the whole of humanity has embarked upon. Being a Western framing it is skewed against or even omits the East.

You’ll know this because whilst walking through the crowds you’ve looked into the faces of a million souls that stare back at you in your difference and that stare tells you that what you have as the centre of your interests may not be the same as theirs.

Of course the principle human concerns are shared: love, hate, war, relationships, jealously, revenge, happiness, marriage and so on.

Also, those elements identified by Western theorists who are on the grand voyage to identify ‘the good ship digital’ are also shared – transdisciplinary understandings, the growth of the internet, the desire for pervasive devices, the long term urges towards having what Star Trek described as the ‘hollo-deck’, the ability to ‘beam me up Scotty’ and so on.

The thing that is different in the stare is the sense that you can gain that our predilections and concerns are just that: ‘ours’ and they’re born from our histories and cultural understandings, just as the Asian mind has its histories and cultural understandings. As Ru, my new Chinese friend tells me as I say to him that the West is decadent in many of its values: ‘Yes, but the East is brutal in many of its values’. This was a very honest thing to say and not necessarily meant in the way we might stereotypically understand it. Decadence is as bad a state as brutality. Decadence can be brutal and brutality can be decadent, but neither value directly follows the other.

The look in the Asian gaze says – ‘it’s my time now and I’m going to find out what that means’.

What it doesn’t mean is the decadent definitions that arose out of the analogue – the traditional academic studies that come through the Frankfurt School, then through the British and then the redefinement of French and American Academia and to some smaller extent British and other European nations, Canadian and Australian, of all of this into what is now framed as pervasive, digital and transdisciplinary and all those other word boundaries that circle this Western voyage – but to borrow a phrase – ‘it’s the whole sea, stupid, not just the bit around the boat’.

What you see when you look into a Chinese face is for a start, many, many different types of Chinese face within which there are many, many different types of soul (no apologies here, the word personality just doesn’t do it). There are 56 languages in China, 56 kinds of people in physiological structure with many subdivisions. But Western definitions are for me to be seen as a start towards a broader project about understanding what the digital is and might be and how it operates for the whole planet. It does a lot of what the West says it does, but that is only a part of the definition of the digital. To use a metaphor of the engine: we are busy looking at the carburettor – there’s still all the other stuff in an engine to understand, pistons, manifold, sump etc, which eventually will make us realise that digitality is not a carburettor at all – it’s an engine, a motive power for fundamental change in the human condition.

We know this on some levels but it’s the form of our descriptions that render us as parochial. We’ve done the best that we can up till now – but now we have to do a lot better and think a lot wider. What am I personally going to do about this? I’m going to try to learn to speak Chinese to at least begin to understand the idiom the Chinese exist within.

A workflow is a map

In having to complete the task of writing a workflow of High Definition technologies, I realise that as I lay each part of the topography of the timeline down, I begin creating a map of the terrain. Between capture of image and its display are a series of processes that affect the data by degrees of limitation – and if you understand this level of digitality, then wherever you are in that digital landscape – and in this case we are in the country of resolution and its near neighbours, ‘significance, meaning and actuality’ – then you can look at the map, know where you are and navigate successfully to your destination...

Some Notes on the Theory and Practice of Innovation in Theatre, Film, Electronic Cinematography, Digital and Television Education

The Fortuny - Mariano Fortuny's design for an early electrical lamp

INTRODUCTION
This article is concerned primarily with what constitutes the need to innovate due to practical pressures - and given I was a Director of Photography for a quarter of a century I will utilise my own work and its pressures in practical situations to reveal as much as I can about the process of innovation. I will also discuss the teaching of lighting and some of the methods I had discovered to reveal the sensibility needed by the fledgling Director of Photography that intuits and senses the materiality of light, so that that person is then equipped to solve lighting problems outside of mind-sets which engender and replicate what is expected in standard film and televisual forms. To be an art, lighting must not be standardised, the pursuit of the photographic moment within the flow of cinematic frames is a quest and an art outside of the act of standardisation.

The demand for innovation has developed within the art of lighting partly through budgetary pressures - in fact I will argue that the main development in lighting in the 20th century was due to Nestor Almedros, a Spanish Director of Photography working in Cuba, who had to think outside of his experience with little or no budget - due simply to being provoked by a mirror being smashed. Equally one must look at the career of Mariano Fortuny, also a Spaniard, born seventy years before Almendros, who was responsible for defining modern theatrical lighting. Fortuny was a wonder, a painter who Klimt took advice from on the use of gold in painting, a textile artist and designer who looked back to the Egyptians development of pleating materials, who the Japanese designer Issy Miyake, born 100 years after Fortuny, took inspiration from to develop his pleating methods in the 1980’s; Fortuny was also a designer of early electrical lamps, who was engaged by Toscanini to design lighting for a prodiction for La Scala which led to the invention of the Fortuny Dome that then prompted Fortuny to create the basis for modern theatrical lighting grids. At his studio in Venice, Fortuny later encouraged the experimentation with 35mm film projected on to textiles and paintings - surely some of the first experiments that questioned the notion of ‘the screen’. He seemed, given the analogue technologies of his time, to have no disciplinary boundaries.

Video Painting, a projection on textiles, 2009, by Artist Charlotte Humpston, who began her training as a Theatre Designer at Central St Martins

In all of the above there is also the issue of the relation of practice to theory, of theory to practice and the perennial question of which should precede which and which of these should be informed by the other. In each of these two practices there are two different languages used. Theory seeks to be as precise as possible in the revelation of the truth of the act, culture or thought. In so doing it utilises metaphors that are as precise as possible. For instance the term data-mining is concerned with data as having multifarious levels and so the concept of digging out meaning is evoked. However, dealing with data has nothing whatsoever to do with the act of mining. Coal and minerals are real and not virtual. Data up until recently, has been described by contemporary media theory as being immaterial - although this is questionable for a variety of reasons that are outside the purview of this article. The point is that those involved primarily with theory, pride themselves on precision yet because they have to rely on metaphor which must break down at some point, can be said to utilise imprecise methodologies.

I do not wish to bring down upon myself the wrath of academia and those who’s job it is to practice theory, to be overly concerned with this argument. I simply raise it as we do need at some point to deal with this issue. Those concerned primarily with practice, it could be argued, do not concern themselves with this viewpoint as, it can be argued by practitioners, that that which is evoked in the act of theorising, damages the ability to be fully involved with practice. Practice utilises a different language and approach from the act of theorising. Often the language is imprecise and purposefully not rigorous (having said that, teaching of craft practice is rigorous in certain ways i.e. the relationship between f stops and depth of focus for instance is a mathematical relationship and therefore by definition its teaching can be rigorous). However, I am here thinking of practice in a real world situation which is rigorous in professional terms but also requires - if the director of photography is to ‘say’ anything with his or her work - the courage to go beyond being rigorous and therefore being safe, to an operating space which allows for accident and unusual solutions which align more perfectly with the intent of the scene they are lighting.

In the introduction I was fully aware of the use of imprecise language: ‘the fledgling Director of Photography that intuits and senses the materiality of light’. The use of the phrase ‘materiality of light’ does not bother me. I know it to be true. In the job of DP you touch light every day - put out your hand, introduce a finger before your palm and produce a shadow. That is fully material. What I was referring to was the use of the word ‘intuits’.

I use this word and idea in the sense that the DP enters the space and must dismiss the use of logical beta-thinking, frontal lobe ratiocination that gets in the way of the evocation of the sense that then recognises and produces a comprehension of the state of the space, in terms of light. This is intuition or in-teaching - listening to what is being told to you inside of yourself - maybe by yourself if no other. Actually, this is precise in description because this is what happens if you do not follow a systematic approach as taught with contemporary educational film and video courses, which emphasise functions like ‘key, rim and fill’ as a basis for lighting. In truth these are simply starting positions to develop 'photographic lighting' as espoused by great cinematographers like Conrad Hall (his last film, Road To Perdition) and for 'craft' to flourish within academia, as it does within Hollywood, we must encourage a definition of the characterising functions within a developed sense that we hardly recogise as being of worth study, goes under the guise 'intuition'. It is said within the industry that 'you've either got it or you ain't', but that conclusion is in fact a descriptor of the condition of the students mindset after academic training in practical motion picture and media production studies.

Key rim and fill, or, Three point lighting

A HISTORY
I have been a Director of Photography in the UK and have been lighting since 1980. I'm currently an AHRC Senior Research Fellow at Bristol University. When I first took up the craft I was privileged to be working in the middle of Soho in London catering for a blossoming TV trade – it became important to learn the skills of lighting. Many years later, after numerous commercials, promos, TV dramas and four feature films I now try to give back what I’ve learnt, to the industry via teaching the incoming trainees that now flood into every educational institution around the world: Making moving images has an allure for young people developing within the digital age, sufficient to disable the call of the young to rock and roll a generation earlier.

When thinking as a DP, sometimes there’s a challenge to try to think outside the box to solve a lighting challenge – usually due to budget. Some years ago a friend of mine was directing a music show for Channel 4. His DP was about to be fired because he’d been asked to light the set low key, but to keep any presenters or acts lit high key. This conundrum blew his fuse and he retired. I got the call and said I could solve the problem. Then I sat down and started musing on the problem. After puzzling over it for a couple of days, suddenly a solution came to mind: fortunately for me I’d seen a documentary on Cuban cinema a couple of months before. They didn’t have many lights available in Cuba at the time and so they took to carrying them around on the ends of boom poles, so that when people moved the light moved with them.

That’s when I invented the ‘Ned Kelly’. I asked my partner who is an art director to make up a chicken wire cylinder about 15 inches high by about 10 inches in diameter. I cut out a slot about 8 by 10 at the front and put two layers of frost there, then coated the rest in black wrap. I hung a 1k lowell tota-lamp at the back shining through the frost and hung the whole thing off a barracuda pole or polecatThe English sparks weren’t too keen on a job where they get to carry poles around with lights on the end, but after a while everyone warmed to the task and we got a low key show with high key presenters. I mention this here because this article is about invention and how one has to look at the world to then invent either a lighting unit or emulate a lighting effect one sees happening – and also about two men who have changed the way we light: Nestor Almendros and Mariano Fortuny – both Spaniards.

Some years before I had to go to Russia and there was a neat little collapsible trace frame available that I took with me: a great solution for merging the output of several lamps and therefore having only one shadow. If you go traveling to shoot a documentary you don’t have many lights along with you. When I shot the Patriarch of all Russia (during Glasnost) the man saw a bizarre combination of two trace frames with blue gel over it and 4 lights passing through them: Double softness corrected to daylight.

When I got back I thought I could refine this idea somewhat: I invented something I jokingly called the Flaxbox – I’d heard a few years before that Jordan Cronenwerth had invented the Croniecone for Blade Runner – something to slip over the front of a 5k or 10k to get soft light out of it, so I figured if he could call his unit after himself – so could I. I took the collapsible trace frame that was roughly 36 inches wide by about 30 inches long. I again asked my partner to construct a black material cover fortified by art card with a 12 inch central square hole in it.This could be mounted on a stand. In the middle of the square the front protruded out by one foot to make sure that light did not spill around the subject. At the back of the frame I suspended a layer of trace, half way down the one-foot square protrusion I mounted another layer of trace. This provided double softening and a form of elementary barn door to specifically aim the soft light wherever I chose. It became a very beautiful portrait unit for various situations. The light was so soft you didn’t need any diffusion over the lens. You could put a small pepper light through it, a 1k, 2k or a 1.k2 or 2.5k HMI or any combination of lamps– whatever you put through it became one soft light source with hardly any shadow.I used to carry this around with me and if I got any difficulty from the star, including people like Mariah Carey, (who is astute enough to take her own DP around the world with her to make sure they were represented in a particular kind of way), then I showed them what I was going to do by sitting in front of my own lamp. Sometimes I didn’t light the star but the presenter and my presenter was watched by the star and embarrassing questions were asked: I remember doing a job for the BBC where a very big star had a full time lighter. I let him do his job then lit my interviewer and this particularly acutely bright woman saw the image on the monitor and demanded that she swap places to get into the presenters light. I don’t know what happened to the full time guy after this.

TEACHING
I sometimes teach one or two day lighting courses and I pride myself on an apocryphal history that takes into account all of the accidents that fill the annals of our craft that stem from low budgets but then provide the most interesting lighting techniques: i.e. low budgets on quota quickies produced film noir lighting – the thinking was, if you do a ‘proper job’ because you haven’t enough lighting units and crew, then create shadows for dramatic effect.

On these courses I tell my apocryphal history starting with the idea that everything in our world can manifest an image. If you leave a stone on another stone long enough then a shadow of that stone will be left. Of course that idea leads to the idea of ‘film speed’ measured in ASA or DIN, which at the very beginning were around half an ASA.

So, on starting my class I ask one student to sit in front of the class and in front of a camera and another student to turn out the light on the cue of the word ‘light’.
Then the classroom is plunged into darkness. I wait for a little while waiting for people’s sensory systems to settle down and move around so that they become aware of sound. I then turn on an angle poise and move around the subject aiming the angle poise at them and ask the remaining students to note what looks good and what doesn’t and then note where the light is.

I then talk about creating separation when you have hardly any tones in black and white, and the simple development of sets outside that can be slowly rotated to face the sun…. I speak about film speeds increasing and therefore having the development of a key light that replicates the Californian sun’s height and the beginning aesthetic awareness that offsetting its angle to the face to avoid direct to full face lighting creates modeling on this egg shaped object we have on out shoulders. I talk about how the Californian sun is low enough to get under the brows and show the eye sockets – but that when the key light is offset you need a fill light to fill in the nose shadow at lower intensity to the key light – and so on.

I talk about placing materials in front of lights to mitigate their hardness and about placing materials like stockings in front (or behind) the lens to affect the way the light gets to film. I talk about Marlene Dietrich and Greta Garbo liking particular cameramen because they kept them beautiful for camera – I talk about the development of film noir – and eventually I come to the seminal moment of modern film lighting experienced by a Spanish cinematographer working in Cuba.

In my lighting classes I demonstrate the effects of all of these different things. I get the students to take on practical challenges to find out things – if this is how you light one seated person – how do you light two? I begin with the very first moment when I get a student standing by the light switch and on cue turning the lights off at the first mention of light and keeping the students in the dark whilst talking about the beauty of light and letting their sensory systems settle down into dark mode. All the way through I tell them that their aesthetic is what they must develop and that this is characterised by a set of likes and dislikes about what is good and fitting and most importantly with a discriminative mind that understands how what they like is produced and how to deduce how what they are seeing on TV and at the movies is produced.

But then the moment comes when after 50 or more years of hard, direct light (albeit greatly moderated by various techniques – and also the advent of 9ASA Tripack Technicolor after the war – suddenly the moment of transition comes. I show them a 100% increase in quality of light over all that has gone before and then tell them the tale of how it came about:

SMASHING THE MIRROR
Nestor Almendros was born in 1930 and brought up in Barcelona – a Spanish cinematographer. He immigrated to Cuba in 1948, where he began making amateur films with young Cubans friends, including Tomás Gutiérrez Alea. He later studied filmmaking at the Centro Sperimentale in Italy, and supported himself in New York as a Spanish language teacher, while also conducting his own experiments in cinematography.

Nestor Almendros 1930-1992

Following the Cuban Revolution in 1959, he returned to Cuba, where he secured a job with the state film department, making films for the Cuban Government. One day whilst filming in the interior and because there was no electricity to be had, Almendros had to rig up a mirror, a techniques he had developed, outside the front door of the building, then aim it down the passageway onto another mirror which shone directly to a third mirror which then angled the light at the subject.

This alone should be enough to take the breath away in terms of invention. Yes we’ve all done this sort of thing but to be doing it so far back with film that was possibly only maybe 25 to 50 ASA – that’s stunning. But then something happened, Almedros heard a crash whilst setting up his first two mirrors and found that the third mirror had fallen and smashed but that the beam of light hit the white wall and created an almost holy glow around the subject. Almendros was transfixed at its beauty and proceeded with the work – transformed.

Director Terence Malik and Nestor Almendros' 1978 Days of Heaven, shot mainly at 'Golden Hour' - that mysterious moment after the sun has set, yet light is still in the sky. If you look you'll see that 'fill' light is bounced back into frame from the left.

His work was seen in the Paris documentary festivals of the next few years and the audience members, Goddard, Truffaut, Rohmer etc –saw that his work was great and by 1964 he shot Eric Rohmer’s segment of the Nouvelle Vague portmanteau film Paris Vu Par (1964; Paris Seen By). Then in 1967 he shot Rohmer’s feature film La Collectionneuse - he went on to shoot seven more films for Rohmer (among them, Ma Nuit Chez Maud (1969; My Night at Maud's), Le Genou de Claire (1970; Claire’s Knee), and Die Marquise von O… (1976), and nine for Francois Truffaut (including Domicile Conjugal (1970; Bed and Board), L'Histoire d'Adèle H (1975; The Story of Adele H), and Le Dernier Métro (1980; The Last Metro). Almendros’ invention of bounced as opposed to direct light was favored by the film-makers of the New Wave because of its realistic feel in opposition to the glamorous techniques of mainstream cinema.

Almendros then made his first foray into American film-making with the Roger Corman-produced The Wild Racers (1968) and Cockfighter (1974), but it was with Days of Heaven (1978), directed by Terrence Malik, that he made his name in America. In the film, shot in rural Alberta, Canada, Almendros abandoned the artificial effects employed by modern cinematographers in favor of natural light. The deliberate simplicity of Almendros’ technique led to conflict with the film’s technical crew, who were unused to such austerity, but the results were exceptional, bringing Almendros an Oscar for Best Photography. Make no mistake – though all inventions are a result of the development of the Zeitgeist and many photographers were heading in this direction – really, the invention, or rather paradigm change of that of mainly using bounced light came from Almendros.

At least that has been my apocryphal tale up until very recently. Here, by the way, I make no apologies for inaccuracies and inconsistencies in my tale save that the basic truth of it is right because it is a question of inspiration when teaching and pulling inspiration, intuition and creativity out of those you teach and if I have to get them into a more visionary space by creative inaccuracy – then so be it. But, just to set the record straight here is a passage from Almendros’s book, ‘A Man with A Camera’:

Working in the countryside and in places we had to use our ingenuity to film inside the huts of Cuban peasants. We had no artificial lighting because it was expensive to take a crew of electricians with us. We thought up the idea of using mirrors, capturing the sunlight from the outside, reflecting it in through the windows and directing it to the ceiling, from where it bounced and lit the whole place. Because the huts were rather dark and the walls dull-colored, we had to cover them with white paper to reflect as much light as possible. I should point out that around that time fashion photographers began using light reflected off white umbrellas. I knew about these methods, though as yet they were not much used in filmmaking. They were techniques I perfected later in France.

Well, the story I’ve been telling is near the truth, but here’s the thing, I think we can all agree that bounced soft light is what the industry is using worldwide – yes it takes more control, flags, baffles etc, but bottom line it’s where we are now. For a start, soft bounced light makes the hideousness of the live digital video signal feel a bit better – whether it’s a ghastly little Z1 all the way up to an Origin, Genesis, F23 or Red – soft light begins the cinematographic process with video – and film just loves it (of course film loves all sorts of light that’s why everyone just goes fluffy when using film).

Julia Jackson by Julia Margaret Cameron, 1867. There is hard light source to the right of this picture, but there's also a soft bounce coming in from the left - just as with Nestor Almendros Days of Heaven image, above.

I think perhaps Julia Margaret Cameron may have known about bounced and reflected light and then later, when movie film became fast enough for interior studio use, the great banks of mercury vapor lamps might also have been emulating the kind of work that Almendros was to later come upon and develop.

So, though we need direct light to create certain elements within the frame we’re can all agree that soft light is useful and contemporarily dominant? Well, just to challenge this history I’d like to introduce a new idea: in 1904 there was a Spaniard (yes, that nation does have an edge on others in the invention of lighting techniques) called Mariano Fortuny. (I make no apologies in an article of this sort for my next point: Next time you go to Venice, go to the Fortuni Museum, which is Fortuni’s old residence of the Palazzo Pesaro degli Orfei – it’s a museum like no other in the world. This is a museum where the muse descends and accompanies not only the artist, but the visitor).

PRIOR TO THE MIRROR - THE DOME
Mariano Fortuny was born in Granada in the Fonda de los Siete Suelo at the foot of the Alhambra on 11th May 1871. In 1874 his farther died in Rome and in 1875 his mother Cecilia was induced to move the family to Paris. Fortuny copied a Velasquez at the age of 9 and he was sent to learn at the feet of Benjamin Constant. Fortuny frequented the studio of Rodin when he learned about liberating the form from the stone.

Mariano Fortuny 1871-1949

Fortuny was restless in his enquiries about materials and techniques and he was stimulated by the early technical innovations such as that of electrical lighting – this became a dominant idea in his mind as he discovered through a friend of the family, a painter named Boldini, the theatre. What really captured Fortuny’s imagination was a trip behind the scenery, where he saw what the magic of theatre was constructed from which is of course very similar to motion pictures – bar the medium of recording and inscribing the image of course. For Fortuny though, he began to build small models of theatres and sets and he then also became involved in thinking about the possible applications of electricity, physics and optics in the theatre. It was this period and being shown deeper elements of the construction of a theatrical event by a Spanish painter, Egusquiva, that were to stay with Fortuny as he began to invent new techniques of theatrical practice that will be recognized as being at the base of contemporary theatrical technique – as well as being at the base of cinematographic technique!

In 1889 Fortuny’s mother moved the family back to Venice where their house on the Grand Canal became a busy meeting place for artists and writers. Not only did Fortuny paint and etch and practice all of the traditional methods for studying art, he also practiced music, photography and set design. By 1899 he had grown enough to be commissioned by a Countess Albrizzi to design the set and costumes for The Mikado. He then obtained the top floor of a Palazzo where he eventually came to live and it was here that he began his studies of light and experimented with lighting systems finally developing his indirect lighting system:

In the attic of Palazzo Orfei where I worked, the sunshine fell across the floor in a clean slash. As I was arranging the paper for the stage backdrop, it fell exactly into this sunlit area. I stopped in surprise. There, in that low and dim attic, the light that was reflected off the paper was exactly what I had been looking for: not direct light, but reflected light.

In a production at La Scala with the orchestra directed by Toscanini, Fortuny developed sketches for costume and set and with some opposition from La Scala’s stage technicians, he also attempted to implement parts of his new stage lighting system. The technicians may have been suspicious, but the press was ecstatic with the lighting effects and he then registered his first patent for an ‘indirect stage lighting system’. He went to Paris in 1902 and dedicated himself to the construction of stage lighting equipment and to the creation of a device commonly known as the ‘Fortuny Dome.’ It was a concave quarter sphere that was used with his indirect lighting system to enhance the depth effect on the stage set.

With the help of my capable technician, I built my dome of out of plaster 5 meters in diameter. We projected reflected light upon it and added other colored lights, creating fusion and transition effects and a variety of hues that invariably impressed all visitors.

On 6th April 1904 he registered an invention entitled ‘Systeme de constituton d’une paroi concave au moyen d’une capacite gonflable'. Fortuny had created a dome for the Countess and added the following refinement: The walls of the dome were made of two parallel layers of fabric supported in a metal frame. A fan blew air between the two layers, creating pressure and making the surface toward the stage completely smooth. In addition to his complex stage lighting system, Fortuny had the chance to install other new equipment in the theatre. For the first time, he introduced a bridge and then a second walkway above the stage, used by stage technicians to mount the lights. Not only this but he created a system to raise and lower the stage and for the first time ever in the history of theatre, he installed a director’s booth at the back of the auditorium for the lighting operator, who could better direct the lighting effects to the stage.

I’ve used the term ‘theatre’ in a lot of the above description of Fortuny’s activities, but it shouldn’t take much imagination to see what effect Fortuny has had on contemporary lighting and also cinematic studio design. But – not only this. Fortuny created designs for fabric, patented carbon-pigment photographic paper, advised Klimt on the use of gold in his painting, created set design and lighting effects, photographed, played music, researched the history of fabric and created pleated silks inspired by Egyptian Design that later influenced Issey Miyake’s work in the 1970’s and onwards – and, invented many domestic lighting units that are now present in their modern day forms in every household. His wood and metal table lamp of 1929 is the ancestor to Pixar’s dancing lamp.

The three lamps other than mine shown in this article are designed by Fortuny - if you have time, search the net and have a look at the wit, intelligence and inventiveness of the man in his other design work in lighting, textiles and paintings.

Many distinguished cinematographers and gaffers create lights to do specific jobs – Jordan Cronenweth’s famed Croniecone used on films like Blade Runner are a case in point – but, can you imagine a moment perhaps in the 17th Century, or the 6th Century – or maybe way back in our collective pasts where some bright person noticed and became transfixed by the way light bounces, reflects, glows, or passes through a medium like water or smoke and has an epiphany that is then translated into a practical act: for those of us that work with light, that most insubstantial but most powerful of materials, I think it helps to know that we exist within a tradition that goes beyond the birth of cinema into the history of theatre, and should one cast one's mind back a little further to sixteenth and seventeenth century masques and their lighting effects and back further still to Roman, Greek if not Babylonian forms of entertaining one another.

At the beginning of this article I had said: ‘This article is concerned primarily with what constitutes the need to innovate due to practical and budgetary pressures’ but I also tried to foreground issues around the teaching of practice and the theorising of practice - as well as the practicing of the act of theorising. What I have also been interested in as an underlying motivation in the writing of this is to celebrate the different but similar modes of thought between the production of recorded media such as film and television and live media such as theatre or performance art. It is clear to me that there are shared ideas in creative innovation in any medium because that act of invention itself evokes the use of sensibilities that are outside of formal ratiocinatory thinking. One is essentially looking for everything that exists outside of the acts that lead to thought that easily enter language or more specifically, text- and in contradistinction to the spirit of that idea, it has somehow found its way here.

REDaesthetics and the Art of RAW

For an assessment of my research, please see the blog entitled Time and Resolution: Experiments in High Definition Image Making, which outlines my work and current findings. Another set of ideas I've been working on, in terms of how colour is represented can be found at: The Concept of Colour Space from the practitioners Standpoint.

‘RED aesthetics and the Art of RAW’ is an event to be held at the Barbican on Monday 26th April 2010 and explores how changing technologies are having an impact on the practice and aesthetics of cinema and moving-image arts.
 
As an event it is intended to get under the skin of what digital is and means, or can mean for artists and filmmakers. The debate was prompted by the arrival of RED camera technology and its impact on the film industry. A central question was: Can it also be a good thing for artists and individual filmmakers, or does throw up new issues and problems?

Here are the series of questions to be asked and my response to them - I hope there's something in this that reveals something about High Definition thinking.

How is it different to film? Are the differences substantial or superficial?

Electronic Cinematography and Photo-Chemical Film are materially different
The real issue is their similarities because their difference is their materiality.
Their similarities lead to confusion.
They both record images with a similar latitude of response, they both have a latent image state and then a way of bringing the image via development and rendering into a material state. There are similarities of post production. They both end up being displayed.
Digitality enables the prior technology of film to distribute across its sister medium, the internet.

What do those differences mean for artists and filmmakers?

If treated in the digital realm - not a lot.

Are the differences just relevant to artists to whom the material is part of the work?

The differences are relevant to cinematographers and adherents to the prior paradigm of film. Film thinking remediates digital thinking - like painting did to photography.
 
Is the digital image a different thing from the film image? If so, how is it?

Basically yes - but the question itself turns out to be complex:
Depends on where you are asking in the process. In capture, in workflow, in post-production, in display they all differ through their materiality - if at any point you cross-process then each material takes on the qualities of the other. Also the digital image is different from video which can be either analogue or digital. In fact digital imaging takes much from its analogue predecessor. It should also be noted that the first adherents of video art were film avant-guardists who had remediatory concerns and and produced muddy outcomes on analogue and digital video for years.

 
Do new forms always and automatically mean new options for artists?

Unequivocally - Yes! That’s what modernism brought to the party.
Of course modernism wa the rejection of art as determined by the invention of the printing press and exemplied at its apogee by the Frankfurt Schools ‘reading’ of art as something that requires ‘interpretation’ to reveal it’s point, its truth,, its significance. With the advent of the digital, text based analysis and the requirement for the artist to encode meaning and the audience to decipher that meaning became obsolete. We are currently stuck with this old form until more advanced ideas become articulated with what is actually happening within audience experience which is one of ‘entrainment’ rather than interpretation.


Are artists lead by technological developments? If so, to what extent?

Always and never. Some go their own way, some listen to the way the world is through technological advance. Its within the dominant ideology of this time - the tale end of modernism with late capitalism.
 
Artists such as Steve McQueen and Issac Julien use professional DoPs for their work. Does this alter its status in terms of authorship? Should these works be thought of as collaborative works?
Walter Benjamin asked in 1936 whether or not whether the replica can have as much aura as the original artwork. In 1987 Illuminations made a programme to start the satellite arts channel called L’Objet D’art dans l’age electronic - Can copies of the object of art have aura. In the digital realm there is neither copy nor original - where does this question lie now?
All artists use craftspeople to accomplish their goal if they are within the modernist ideological, late capitalist state as they reject the need for self competence within the area they feel they are empowered to speak within - which is why there are so many babbling voices. The Italians have a saying: Few are called - but many answer.

 
What about technical skill? Within the industry DoPs/camera operators will be trained on RED, but this is unlikely to be the case for artists. Does skill level then have an effect on creation?

This question is about whether or not art is conceptual - or that its assessment is based on criteria that relate to skill. Recently, the only skill relevant to the creation of art has been within the arena of ideas with execution being left to craftspeople - and yet, judgements about absolutes within art are determined by questions of skill. The issue of Leonardo or Micaelangelos reputation - or Vermeer or Titan etc is around their ability to execute their ideas within painting or sculpture. It is their art that is undeniably seen as the apogee of human activity and so by default - carft and skill ARE the determining factors about the potency of art in relationship to its shelf-life.
Artists recognise they have to buy in skill to make their work achieve recognition above the bar that art without craft lies beneath.

 
It has been said that film is ‘truer’ as it has an indexical relationship to reality.
But in fact, is HD ‘purer’ in that it is raw data rather? Does it matter? Is it interesting?
I think there’s a confusion in the asking of this question. Neither medium is more pure than the other. RAW is a state and film information can be encoded in RAW data as much as Electronic information - so I don’t buy one is more pure than the other. They are both materials. Indexicality is a state of mind. If I look at a film or HD image without indexicality as my mode of looking then what is seen could simple be an abstraction. It is only a tendency towards organisation in some minds that create indexicality - and especially those who have inherited aristotleian/enlightenment/victorian cataloguing tendencies that indexicalise the world - i.e. academics. Artists have to develop the opposite kind of mind (unless indexicalisation is their project)

 
Is technical purity/excellence somehow limiting to what artists can achieve? Does it undermine individuality?

Technical excellence is a practice and some philosophies propose that practice - and especially limiting practice like zen meditation - is a key to unbridled comprehension of the world. Also individuality and that neurotic expression, individual creativity, is a compound of the period from the early medieval to the present. We are placental mammals wit placental mammal imaginations. Certain artists sometimes trigger response from somehow being apposite in such a specific way that they earn the cheers of the mass of the other primates - but the idea that individuality being undermined is non-cogniscant of the fact that out profile as individual creatures is severally limited in the first place.
 
Does technical purity/excellence detract from identification/storytelling?

I think we should do away with being good technically as being a problem. It’s true that technical excellence comes with a certain set of values, but if the artist or film maker isn’t up to it then nothing they do will be any good anyway.

A Spring declaration of the Death of Film

For an assessment of my research, please see the blog entitled Time and Resolution: Experiments in High Definition Image Making, which outlines my work and current findings. Another set of ideas I've been working on, in terms of how colour is represented can be found at: The Concept of Colour Space from the practitioners Standpoint. You can find other papers of mine at: academia.edu‘

A few weeks back, with the advent of the Alexa from Arriflex and the new sensor from Red, Marc Weigert an Emmy award winning visual effects designer declared on Friday, March 5, 2010 at 11:03 am in an article on the Film Animation World Network that:

2010 is the year that celluloid Died

For a week or so there was opprobrium expressed in abundance on the Cinematographers Mailing List: “obviously this man doesn’t know what he’s talking about” - others said “let him off the hook, he’s just being enthusiastic” others said - “maybe he’s got a point”.

Well, the cat was out of the bag. A few weeks later an article by Alan Brandon on gizmag (17 the March) asked:

Will the Arri Alexa finally kill film?

The point here is that the conversation’s on. The truth is film will never die or go away - people still chalk images on rock, so by the same token, film is here to stay.

The step-change with the Arri Alexa is that the ideas proposed by many cinematographers concerning getting a full image form a digital camera by shooting two frames one with low exposure one with high exposure - then combining the low lights and the highlights of both so that the final combined frame benefits from both exposures - must mean that the latitude given in the pho-chemical medium of film is surpassed.

However, one rule of electronics is that supposed gains always produced un-supposed drawbacks and we wait to see what the downsides of the new innovation produces.

There’s another issue too: over-exposed film highlights were beautiful whereas over-exposed digital highlights (for various technical reasons) were not. So by cutting out over-exposure digital capture will at least not be ugly in that area. But the hidden loss is the potential absence of one of the colours from the cinematographers palette.

Well - of course until we all get our hands on the cameras and do some work in earnest the jury will have to remain out on this.

One by-product of dealing with so much data is that the Alexa is limited to 2K - therefore notionally good enough to rival the resolution of film’s 6k (I quote the necessary scanning figure for good transfer), baring in mind that by the time you get to a release print with film in the cinema you see what approximates down to 1k (because of the degradation of the various processes film has to go through), and of course HD 1920 or 2k acquisition (2048) screens at 2k - therefore twice the resolution of standard film projection.

The Red shoots at a notional 4k (3.2 if your lenses are good enough) and the unspoken problem in data management is Modular Transfer Function: each bit in the chain of data has a quality level - whatever the lowest quality in the chain is is the MTF of the data. Often, 4k can be below 2k...

The Alexa sensor is running 2 x 2k frames for every red 4k frame - effectively half the amount of data - so if as Panasonic often shout from the rooftops that measuring resolution and anything else come to that, is dependent on the quality of the chain - you better know what the weaknesses of the chain are.

Incidentally - Red can run 120fps at 2k and the Alexa will run 60fps at 2k - that’s the same amount of data.

However:

The point of all of this is that technology is following the aspirations of the DP’s (finally) and we have a good chance in the Alexa of putting out some images comparable to film.

High Definition, High Resolution and Electronic Cinematography

For an assessment of my research, please see the blog entitled Time and Resolution: Experiments in High Definition Image Making, which outlines my work and current findings. Another set of ideas I've been working on, in terms of how colour is represented can be found at: The Concept of Colour Space from the practitioners Standpoint. You can find other papers of mine at: academia.edu‘

New sensors scheduled to deliver in the coming year from both Red and Arri are even more promising. Despite my nostalgic love for film, I fear it may soon be a fond memory on all but the most specialized productions’. Johnathan Flack cinematographer, Cinematographers Mailing list, 18 january 2010.

I’ve been minded to try to summarise what has happened in High Definition technologies for a while now but it was only having to answer the mistaken notion in a recent document that went under peer review that made me realise that the general understanding (of academics at least) is still back a few years in origin. People often talk in terms of High Definition - yet this term alone creates a huge confusion about what is actually going on.

One of the two reasons HD was called HD was to combat Film’s hold on image generation for feature films. Sony and various other electronic corporations needed to rebrand what they were doing to successfully challenge the corporations such as Kodak who dominated production of professional and consumer materials in this area. The other reason the word ‘High’ was used was because the new format was to replace standard definition equipment in one of industry’s new-broom maneuvers which allowed them to sell a lot more product.

I want to cite a distinction that we shouldn’t waver from: High Definition is proprietary in form - that is it comprises of data that is packaged in a particular file system, generally with a pixel count of 1920 x 1080 or the other popular system 1280 x 720, under a certain amount of compression that make is handleable by the proprietors other equipment. In other words when you use High Definition you’re buying in to a group agreement about a set of easily handleable functions that capture an image at one end and and display that image within certain tolerances at the exhibition end. A particular system of compression that is best suited to streaming video, or compressing for DVD or Blue Ray is that of creating Groups of Pictures - say a set of 7 - where the first frame and the last frame have a set of common reference points and the frames in between throw away that information and only update the elements that change. This system is particularly bad for depicting morion as practically everything changes in each frame, but the tolerance of the system is set to limit information - that’s a contradiction. A short Group of Pictures is therefore less qualitative than a 15 picture Long GoP structure.

On the other hand, High Resolution technologies, such as most Electronic Cinematography forms do use a package, but this is for convenience, it’s intent is to retain as much data, or information generated by a photosite as possible. Photosites are locations where light is turned into data. Pixels are not photosites - pixels can be an aggregation of the information generated by several photosites - or just representative of one photosite. The point is the idea of a pixel is really of a value which may be generated by one or more contributing elements.

Compression still exists in this form, but it is limited because the central thrust of this technology is to retain as much data about tonal latitude, resolution and colour from the natural world as possible. Also, ownership exists in this form - Red’s R3D file system is owned by then and no one else. Also it is compressed - maybe to one tenth of the data that was available to the sensor - but, being wavelet driven as opposed to DCT driven (where DCT means Discrete Cosine Transform as opposed to the rival Wavelet Transform version) it is less destructive of the data and information can more easily be retrieved or simulated from this form of compression.

Data cameras utilise logarithmic (log) as opposed to linear colour space. ‘Linear’ is a product of preparing an image to travel through older analogue technologies (phosphorus screens) and therefore has limitations placed upon it to work in that domain. Linear utlised 8 bit Colour and nowadays we are looking for 14 or even 16 bit systems. Log maintains a higher level of data but tends to look not so good on contemporary display - so we introduce ‘look up tables’ to treat the monitor with to make sure the image looks ok on set.

Lastly - data recording means that changes are made to the image after the data is recorded unlike in proprietary systems where treatment are made at the time of recording. Sony was famous for throwing away around 500 pixels in its HD cam system which recorded only 1440 of the 1920 pixels it was trying to represent.

For a masterly description of the discussion around colour space, see Douglas Bankston's article In American Cinematographer, The Colour Space Conundrum. Or my own paper on colour space: The Concept of Colour Space from the Practitioners Standpoint.

So - since beginning my fellowship in September 2007 there has been a fundamental change in the thinking around high definition technology.

Before this time, development of the technology was in the hands of large corporations who employed specialists in various areas to create systems that handled data or information that assembled 25 frames per second into a moving image stream.

Opinion about what was good and what was bad, correct or inappropriate to the process was derived from a cultural attitude assembled through 100 years of corporate development. Research labs, product labs, customer testing and so on assembled and produced the products that industry and then consumers had access to and were encouraged to demand.

From early experiments by John Logie Baird, Vladimir Zworkin and Philo T Farnsworth, modern analogue technologies developed finally via Bing Crosby’s Ampex Corporation into what we now know as standard definition analogue broadcast tv in all of its variants, Pal with 625 lines and 25 frames per second (due to the 50 hz electrical system), Secam with 819 lines, NTSC with 525 lines 30 frames per second (due to the 60hz electrical system) and no colour reference signal, Brazilian PAL with 525 lines and so on, all of which lead towards early analogue HD systems such as NHK’s 1125 line system and Philips Mac 1250 line system.

Due to the persistence of vision factor, where in early film 18 frames per second needed to be held in the gate whilst a circular wheel with two or three slits in it span and allowed two or three flashes per frame (i.e. 18 frames flashed three times was 54 times per second), analogue video needed its 25 frame structure split into two fields to achieve enough flashes per second. Pal with 25 frames, split into two fields of 325.5 lines flashed 50 times a second to create persistence of vision and NTSC flashed 60 times a second. Splitting the frame into two fields is called interlacing and the resulting resolution is half the line structure. 625 lines is 312.5 lines in resolution.

The reason that television as a form developed the idea of interlace (besides the persistence of vision factor) was that the lowest link in the chain was display. Cathode Ray Tubes (CRT’s) worked by having an electron gun fire electrons to excite phosphor on the surface of the screen. Magnets pulled the beam left to right (because were in a society that values that direction more than the Japanese or Chinese), then the beam switched off, another set of magnets pulled the beam fractionally down, the beam was switched on and pulled left to right again. Glass technology was limited to a certain size and electron beams could only sweep so fast before their accuracy was lost. 625 lines was close to the limit of these technologies at the time of invention.

Meanwhile early digital video was developing into digi beta where the remediation of the incoming digital signal imitated and developed into something akin to a line system of 625 lines in Europe and 525 lines in Japan and America. However, there were no lines, only pixels: 720 x 576 in Europe and 720 x 480 in NTSC. Anamorphisation was used to take the European digital system into a 16:9 aspect ratio as it was naturally 4:3 originally. Cathode ray tubes were the main display system and so early digital video used interlace to display the image.

Having established a pixel count the way forward into ‘High Definition’ was established. HD was so-called because the manufacturers were interested in creating a product to rival film and therefore enable them to come into the film market place - they wanted a system that had more Kudos than old analogue terms suggested. Sony still calls its HD system Cine Alta. Due to the financial might of America and Japan. Due to electrical system frequency (50 or 60 cycles a second) a relationship developed, (as it had already done in analogue calculations to derive first 408 then 625 in the European system and in 525 in the US and Japanese system) between it and the ‘natural’ amount of pixels that might easily be recorded and then displayed - From capture through to display is, after all, a chain where the lowest level of information at any point is the determining factor of what the viewer sees - this is the modular transform function of the any system - it’s weakest link in effect in the chain.

So we come to the technology that was prevalent prior to 2007. Having won the frequency battle (50 or 60 cycles per second) Japanese and American manufacturers offered proprietary systems of image capture and display that was sympathetic to the outgoing interlaced paradigm. This meant that we still had lack of a reliable standard between manufacturers because on a financial level - to the victor goes the spoils. This was seen in the early analogue battle between Sony and Mitsubishi who were proposing VHS and betamax. At that time it became clear that the best system might not necessarily win (by best I do not mean most reliable, just best in the sense of image representation - it is arguable that betamax was more fragile on a mechanical level).

What was evident from the start was that film recorded a progressive image and needed many flashes to create persistence of vision and digital video might do this but the forms of display were just developing - so interlace still persists - but it must be remembered that a 1080i picture is only 540 lines in resolution!

At that time computerization and storage was not as developed as it is now and so manufacturers were recognising that though they basically had a standard they could comply to much data had to be thrown away to record an image on tape. The argument about whether 1920 x 1080 or 1280 x 720 was the right standard were still being argued about - where due to simple maths the lower level pixel image could have a greater recording of colour information than the higher level one (also the 720 line system was fundamentally higher in resolution than the prevalent 1080 i signal - it’s only today that we have 1080p in such amounts).

In recording an image the issue is always of how fast your data capture, transfer and recording is (until we pass through the barrier where we can capture and record more data than the eye and brain can see). For me its a question of plumbing - how big are your pipes and your tanks. The manufacturers were using systems of compression and decompression - that is trying to keep as much data as was necessary to fabricate an image that was seemingly high definition.

It would pay to look at the difference between Fouriers’ Discrete Co-sine Transform and Fouriers 1807 innovation which is now becoming the compression system to use - Fourier’s Wavelet Transforms. I refer you here to Astrophysicist Amara Graps work on Waveforms: http://www.amara.com/current/wavelet.html

As Amara says: The fundamental idea behind wavelets is to analyze according to scale. Indeed, some researchers in the wavelet field feel that, by using wavelets, one is adopting a whole new mindset or perspective in processing data.

Then there’s the issue of recording Groups of Pictures or GoP’s which seek to only record the changes in the pictures as they proceed rather than the whole picture and this eventuates in artifacts, blocking into squares that the developed eye finds so painful. This is the system of compression beloved of the internet, DVD’s Blue-ray, streaming etc.

If you have a long GoP of 15 frames where the image is refreshed every 15, it stands to reason that it’s an image of less resolution than a short GoP of 15 (in a nutshell Sony at 15 and Panasonic at 7). This is the basic system in streaming across the internet which is fine in that form (for a while) but there’s no place for it in image capture any more.

Then Red came along to make the data argument public. It’s not that Red were the first, others had proposed systems that did not throw away data, or rather recorded information in packets of data that were less lossy than the proprietary systems (HD cam for instance throws away 500 lines, just like that, so that there’s 1440 lines left to compress to record)

So - the basic change that’s taken place since 2007 is the cultural change that no longer accepts image compression as a de facto stance in image capture and display and would rather have all of the data captured so that choices could be made at varying points along the pipeline about what is kept and what is thrown away.
