This thread doesn't really need to be another tired old Film V Digital, nor even a Defense of the Film thread. Done to death. The original question referred to digital photographers that use software to emulate what they perceive as a "film look". You could push that a bit further. As the original reference was to Ilford, and maybe to digital photographers that strip away the colour data from their binaries, to make b/w. If b/w film had never existed, would modern digital photographers be editing images this way? I'm sure that it would have been discovered as an effect, but would we see so much digital b/w? I have no issue with this practice, although in my opinion, it is often done badly and is presented even worse (such as next to a full colour alternative with the comment "which do you prefer? - usually by now, neither!). Some of my peers shoot b/w in film. Some do it in full digital. The best digital b/w photographers concentrate on it, shoot for it, and present it well. I don't care then if it started out on film or as as electrons. If I don't care about good b/w being shot on a sensor, then I don't care if some people go further and use software filters to emulate film further - except that it usually looks awful.
Culture plays a big part in it. That and marketing manipulation. Sure, Adobe-Canikon and their distributors want us to buy their upgrades, and will convince us that we cannot enjoy photography unless we spend more hard earned money. Alternatively Ilford (albeit a rather smaller company) would prefer it if we didn't. There are large numbers of young people shooting film and sharing it on social networking sites online. Sure you can slander them all as hipsters in a smug way. However, what in culture pushes up the sales of Ilford, Lomo, Holga, and the ilk? Why are digital photographers applying pp software filters to make their full digital images look like film? I'd argue that it is because film has become the alternative. A lot of people, including youngsters, are rebelling (or think that they are) against the same sharp, shiny, technically perfect digitally imagery that is forced upon us in an imperfect world. They want their images to stand out from the crowd, to be individuals in an increasingly crowded society. Even some full digital photographers then try to ape this look, but using pp software.
It is easy to put it all down. But all I know (not as a youngster), is that I like to make images, I like recycling older technologies that I never used in their day, I enjoy the chore and process (the more that you put into each image, the more that you treasure it), I like a pair of wet skinny things hanging over my bath drying, but above all, I like the final results of my home developed b/w film hybrids. They disobey the rules and I crave that. Long live wet things dripping over the bath!
