Reflecting on photographic manipulation

A recent prestigious photographic competition received much wider coverage than such events usually do because the winner was disqualified for claiming that one of his photographs was taken in a particular town when, in fact, it was taken somewhere else. What was less widely reported was that 20% of the photographs that made it through to the final round of judging were disqualified for excessive post-shot manipulation. Comparison with the RAW files was made at this stage and the judges were able to see where objects had been removed, added or moved, and where other adjustments had been made that resulted in photographs that were considerably different from the reality that the cameras initially captured.

I've said elsewhere in this blog that cameras do not faithfully reproduce what the eye sees and if that is the aim for a particular image then post-shot manipulation is frequently necessary. It's also true that the history of photography abounds with images that have been manipulated. The consensus today, is that heavy manipulation is fine as long as it is stated by the photographer, and that "traditional" manipulation - dodging, burning, global increase and decrease of contrast, vignetting etc - are acceptable. The competitors mentioned above did not follow these conventions and also ignored the competition rules forbidding the removal, moving and addition of objects.

I began my photography in the days of film and chemical processing and I find myself in agreement with the consensus. So, in this blog you won't find much "heavy" manipulation, and where it is done it will be stated. But, quite a few of my shots have the contrast selectively and globally adjusted, or vignetting applied, or saturation adjusted (more often down that up, contrary to modern tastes!) Moreover I frequently apply the digital equivalent of black and white filters and sometimes use actual polarising and neutral density filters of one kind or another. I sometimes, but not always, mention when I've made a "traditional" adjustment. Today is an occasion when I will. The photograph above has a global adjustment of contrast and a little blur applied because I liked the painterly look that it confers on the image. But then you could probably have worked that one out for yourself!

Night photography

When I used a film camera the photographic day was shorter than it is now. By that I mean the film that was widely available wasn't at its best when light levels started to drop away. If you used a tripod with a static subject you'd got a chance of a reasonable shot, but hand-held it was a different matter. So, I rarely shot in the early morning or in the evening after sunset. And, of course, those are the times when you can make some great photographs.

That slowly changed with the arrival of digital. As sensors improved we started to use ISO numbers that were unheard of with film. From a film-days maximum of ISO 400 or so we soon progressed to the point where 800 and 1600 were regularly used to good effect. The arrival of in-body and lens stabilisation allowed us to hand hold these numbers quite comfortably at speeds down to 1/15 or 1/8 second despite the fact that often the lenses were not as bright as the 50mm 1.8 or 1.4 that we routinely used with film. Then technology moved on and ISO 3200 and 6400 became viable. Today we see cameras offering 12800 and even 25600.

Consequently, when I'm in London I think nothing of hand holding my camera for night-time shots. Sometimes, if I'm away from street lights and strongly illuminated buildings, I'll brace the camera against a wall or on some railings. I never - thankfully - need to consider carrying a tripod because the results I get hand-held are quite acceptable. We passed Canada Water Library the other day. I first photographed this striking Piers Gough/CZWG designed building at the turn of the year during daylight hours. The night offered a different take on the structure and the opportunity to use highlights on the adjacent water of the old dock.
