I have a plugin that shows what a pic will look like if it was taken in such and such a film. Actually I find it quite interesting playing with it. What you have to realize is that most people say 30 and under have probably not even seen half of these different films. They have no experience with what they looked like any other way and a lot of them they never will due to the fact that many of these films are no longer available anyway. If they have had any experience with non-digital cameras at all? It was likely in their earliest childhood and it was with standard drugstore brand film.
Several of my friends are in their late 20's and they have literally NEVER shot analog, wouldn't know the difference between one brand of film or another. Kodak, Fuji, it's all the same to them. Honestly it's all the same to me. I only know drugstore film. I'm actually trying to learn but that plugin is the only thing I've ever seen that actually gives me some idea of what using particular films might look like versus the drugstore film I'm used to.
I would never try to pass a digital project off as analog, but I absolutely will use that plugin to create something that looks like old film if I want to. Saying that's cheating is like saying that people who used to hand color analog prints back in my great grandmother's day were cheating. They used the tools they had, period.
I would imagine that if say Ansel Adams were alive and sitting here today he'd be astonished at some of what can be done now with a computer and some decent digital imaging software. But what do you want to bet he'd also want to know "how" to do it and that given time he might even want to learn how to do it himself?
Photography isn't a static art form. It's always changed with the times. If it hadn't we'd all be sitting there still loading glass plates and all making our own chemicals. That's not to say you still can't and some might even enjoy doing that, but me, if I can reproduce a "look" I want sans the chemicals and tons of time? I'm likely to go there, sure. Why NOT?
I don't believe in passing off work that's done on a computer as analog work though. If a print is digitally done you should say so, but as far as I am concerned there's no shame in doing it either way. A computer, a plug in they're just tools. As a photographer you use what you are comfortable with and what fits your time frame. For many of us, even those who do still shoot analog, or who have like me come to it lately, that does mean using a computer WITH our analog cameras.
Me, I'm not much into chemicals, and for a very good reason, I'm highly allergic to a lot of the chemicals we all get exposed to every day. More chemical exposure, I don't need, period. I respect those who do choose to use them, but it's not for me. A computer is my favorite tool. I happen to like film too, but I see no reason why I can't have it BOTH ways, and no, I don't think it's "cheating" to develop my film at the lab, scan it and do whatever needs to be done thereafter with a computer rather than with a brush and chemicals.
It's just what works for me.
