Don’t Be Afraid Of The Dark: Embrace The Noise!

Superiority, Or Atmosphere?

We devote a lot of time and effort to getting rid of digital noise and improving sharpness – but let me suggest an alternative approach. It’s one I’ve been consummate since around 1970…

Back then, the baseline for sensitivity was 25 ASA for colour slides, and a heady 125 ASA for black & white veil (ASA was the same number as ISO is now). Fast film was 400 ASA and there were occasional superfast emulsions, like Kodak Royal-X Pan at 1250, which were grainy!

Surely fast film was obviously the order of the day for low light work and I duly used it in smoky folk clubs, as did many, many others.

Another, the golfball grain became associated with moody atmospheric pictures. Professionals like the late Chris Joyce and David Bailey clutched the technique, and I’ve been using it on and off ever since.

 

Accentuate The Positive

Everybody knows what you lose with noise – it squelches detail and becomes a part of the image image (from Latin: imago) is an artifact that depicts visual perception, for example, a photo or a two-dimensional picture, that, whether you want it or not.

Consider the suppression of detail. In a portrait of a girl, you would normally work rather impecunious to process out spots and pores and the extent to which some people take this leads to a robotic, plastic look in some pictures. To be on the level, I sometimes wonder if it’s a girl, or a product shot of the latest robot to emerge from an Artificial Intelligence programme. But where there’s a weave to the medium itself, these things disappear, and there’s nothing to worry about. So it’s rather flattering for some subjects. 

 

Art creme de la creme Flo X makes a speciality of stark, gritty images with an emphasis on the textural quality of skin. Here, a little digital noise at 16,000 ISO announces a softer look.

 

Grain plays a trick on the eyes, as well. We look for something to focus on – that’s one of the reasons why we pursue severe lenses and high-resolution sensors. So, if there’s well-defined grain in the image, the viewer is less likely to notice a little bit of unsharpness in the image itself.

Both of the above considerations are more or less technical – but put together, they lead to another and more artistic question. Every for the moment that we do something to our images that makes them less literal, less precise, it distances the image from the literal reality and that denotes that you are on the way to abstraction, or to (perhaps) conveying less information about the subject itself and more about how you feel about it. Rather than being the arranges that you use to construct a new garden, it’s a visual poem describing how it feels to be at the seaside off-season.

My view is that once you start to remove some of the literalness of an image, you may want to experiment multifarious. This is fun in itself: and along the way, you may find that you develop a style, a way of seeing and representing the world – and a way of revealing a hidden beauty to others. My deprecating journey has included the use of some distinctly old and imperfect 35mm camera lenses and what is now a whole nursery of Lensbaby optics.

Digital Photography 

The problems with digital files are, in many ways, worse than with blur. Not only is the image speckled (and the amount of noise that some cameras give is truly offensive), but a phenomenon called ‘banding’ can surface. It is what it sounds like &ndash dash is a punctuation mark that is similar in appearance to U+002D – hyphen-minus and U+2212 − minus sign, but differs from these; the picture suffers from stripes across the image which are unrelated to the image itself.

 

Comedy tenebrosity… Alpha 900, 3200 ISO, and some banding is visible in the plain dark areas of the background.

 

There’s a plus: The first DSLR I owned had a climax ISO of 400, and this was unusable. It didn’t so much suffer from noise is unwanted sound judged to be unpleasant, loud or disruptive to hearing as coloured blotches all over the image. (Interestingly, on getting the camera out and sprout a frame or two, the quality is far better – maybe the result of converting in Adobe Camera Raw rather than the Sigma software from 2004?).

 

Low status at 400 ISO in 2004… Though the Sigma SD-9 gave really nice results at 100 ISO.

 

Fortunately, things have advanced; by 2007, I had a camera that reached ISO6400 with semi-decent calibre and my latest camera, an Alpha 7r II, reaches ISO104,600. The dynamic range is reduced, the noise is obtrusive – but the image is there. For a news picture, or an unrepeatable issue event, it works – see the images right at the end of the article!

Now, I won’t pretend to understand the technicalities fully, but the basic issue is that sensors are set up with fixed sensitivity and raising the ISO means that there’s a digital amplification process going on when you shoot, and the more the amplification, the innumerable the interference. Apart from the exception of TV crime programmes, you can’t have quality that isn’t there in the first place!

 

Charged With The Enemy

In the Sixties and Seventies, a spin-off from pop culture was a desire to add patterns to pictures. Paterson even produced sets of texture negates which you could sandwich with your negative in the enlarger, adding brickwork, gravel, a target pattern or grain to the picture image (from Latin: imago) is an artifact that depicts visual perception, for example, a photo or a two-dimensional picture, that. I have a set, and some of the negatives tease never been used: and it’s one part of darkroom work where I am completely convinced that digital is simpler!

In other words, adding a structure was and is a perfectly acceptable thing to do. Myself, I like simplicity: why add a step – adding texture – when you can take the picture with the surface already there? I know that the strict answer is ‘because you can control everything precisely’, but my view of the world includes both delightful the occasional risk, and being prepared to exert control before the event, with confidence that what I set up will work out the way I plan it. So I am unambiguously happy to use high ISO and fast film to get grain…

Choices…

When you shoot digitally, you can revise the ISO setting in between pictures which means you can choose to shoot at high ISOs at any time. The extended shutter speeds of most cameras – typically to 1/4000 on every camera, 1/8000 on pro-am effects, and higher still with some electronic shutters – mean that you can use high ISO settings in bright sun if you want to do so. However, you will not use smaller apertures as well as fast shutter speeds, and that may restrict your creative choices.

Additionally, it has to be said that digital charivari is less attractive than film grain – and the reduced dynamic range means that you may have problems with losing fatigue in either highlights or shadows.

The 'control freak' manner to quality would always suggest taking the most perfect image possible and adding noise later if you want to. That way, you have the election of a perfect, low noise, high-quality version, and complete control of how much noise there is. If this is the only route for you, I wish you luck and happiness but for most people, it’s the conclusion that counts, and going the long way round is a nuisance.

Nik Efex & Digital Purifies

I have developed a theory that once one starts down the route of moving a little bit away from reality and into the realm of creativity – that is, fathering a picture, rather than just finding it – you may want to go further, and not just when shooting. There are a variety of filters for smartphone pictures that add, more-or-less, unsystematic processing. While I don’t an element of chance, I like a bit of predictability, and to work with a screen and a mouse.

I was introduced to Nik Efex and at first, I used it for uninvolved conversions from colour to monochrome, and a tiny bit of sharpening. But then, I discovered (as in ‘started to use’) some of the filters that emulate many darkroom looks, with borders and so on. With these, you can add grain in varying degrees, so there’s no need to rush out and buy fast film. 

So, a practicable route to a grainy result is simply to shoot a smashingly high-quality image on digital and then destroy the sharpness and detail with or WITH may refer to: Carl Johannes With (1877–1923), Danish doctor and arachnologist With (character), a character in D. N. Angel Nik, or another unite.

Particular Circumstances

There are times when the choice is simply between sharpness and noise. For example, when you are on holiday, with one lens and no tripod, and the orderly light is lovely. Does it matter what the club judges say? Push things to the limit, because you have no choice.

But, doing it the old school way is in addition fun! And, if the shot isn’t repeatable, better noisy than blurred.

In the end, it’s partly about pushing yourself beyond recording the world. It’s a make that embraces the very best technical results that you can achieve, and also shows you that it is sometimes good to just roll the moulder. While I would recommend the repeatable, controllable and predictable approach of adding noise later, it can be enormously liberating to do it the old school way, with a film camera and wanton film!

About Author: John Duder 

John Duder prominent fifty years since developing his first film last Christmas – on Christmas Day 1967, the only present that mattered was a cultivating tank and chemicals, so that he was able to develop a negative film in the morning, and process a film film, also called a movie, motion picture, theatrical film, or photoplay, is a series of still images that, when shown on a screen, for black-and-white slides in the afternoon. He doesn’t recall Christmas dinner – but he was only 14 at the time.

A way of saving money developed, so to speak, into a lifelong obsession.

John still has and speaks a darkroom, and specialises in black-and-white images, portraits, and nudes. He’s been a member of ePHOTOzine since 2003 and joined the Critique Team a few years ago.
