The idea of taking a picture, knowing that it will be exposed poorly and thinking, "I'll just accomplish these things on my computer"
Statements like this strongly imply that people are actually out there, actively thinking to themselves WHILE SHOOTING, "I'll INTENTIONALLY expose my photos badly, and then just fix it in post. Yes, let me see - all I have to do is move that exposure needle away from the middle, way off the scale, and I'll have EXACTLY the bad exposure I'm looking for."
And that, my friends, is just pure BS.
Ever notice how most of the "purists" who make these kinds of arguments about how people just expose badly while thinking, "I'll just fix it in post", usually supplemented with the argument about how photography shouldn't be about spending time in front of the computer and how they don't enjoy the editing process, also admit in other threads that they basically suck at the editing process because they haven't taken the time to actually learn it? To them, that's not part of photography, while to those who aren't put off by it, it is indeed a part of photography, just as the darkroom aspects were a part of photography to those who worked in the medium pre-digital.
Meanwhile, who really cares? Do what you want, the way you want, and don't judge others for doing it differently.
Gee, there's an idea.
