We live in a world surrounded by, and created from "art" to say that it needs a specific thing or condition to exist is IMO to not really understand the nature of art and that mindset might hamper a persons ability to appreciate the world around them. I also think that people who try and fight the democratization of art are really just desperately trying to control the discourse concerning what is and what is not art, or what is good and what is bad art.
I think that photography and digital graphic arts have merged a bit to create a fuzzy boundary. Reproducing the effects that one could achieve in a darkroom vs the adding of layers, HDR and what not has made the post processing realm an art form in itself. Heck, my final pictures processed from Raw files look almost exactly like the JPGs right from the camera, only cleaner.
I think I've said it here before, 1/2 of the enjoyment for me is the physical act of photography. Getting out, using the camera, looking for the shot. I only post process to get prints and share with the community. Except for a few occasions, few outside of myself and my family would call my work art though 🙂
