BTW, here's the Guardian totally missing the point and letting the subject matter dictate integrity:
They also head down the "since it's taken with a camera, nothing is reality" straw-man route as well:
"Elliot was on to something. Further investigation revealed that the Great Satan was a serial Photoshopper, once digitally removing a shadow in a sunflower field and replacing it with a sunflower, another time manipulating small wildfire flames to look like ever-so-less-small wildfire flames. So he was summarily sacked. For, after all, in violation of all that is sacred, had he not deliberately misled the reader by manipulating the image to suit his narrative purposes? Yes, he certainly had.
Exactly like every press photographer does at every newspaper every day and always has. Every photo cropped to eliminate extraneous imagery and every single shot selected from a roll of 24 deliberately portrays time and space to suit a narrative. So does photo processing, depth of field and aperture selection – none of which is neutral. For that matter, every snap represents the photographer's choice to focus on what he or she is focusing on. Manipulation, editing, selective reality: it is the essence of photography. That's what they give out the prizes for (plus luck)."
Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.
