I'm not quite sure this is a new or novel thought. We have been dealing with this issue since my days as a newspaper photographer 10+ years ago. Back then we would be criticized for flipping a photo or burning/dodging. (for flipping, we would reverse it so that the person's face was looking inside the newspaper if the space for the photo happened to be on the edge) We did not manipulate the actual photo, but rather flipped it inside out. Some people took offense to that. We came up with some rules that most publishers follow. Adjust levels, rubber stamp dust, sharpen, and finally crop. Most things outside that realm were not allowed for newspapers. I see both sides though as people can create some really wonderful pictures with photoshop. (I have done tons of heavy manipulation for college yearbooks etc.) I think the problem lies where people try and pass it off as real. I think everyone should know right from the start whether it is authentic or manipulated. Photography like I use to know it is dead (film). However, digital photography has developed into a new artistic medium I never thought was possible and I like the direction it is going.
