Good article to think about the nature of photography.
Do we create value via destructive means? Or are we just capturing the real moment without any influence on the subject?
A friend who have been a judge on many photo competitions say that while they try to weave out such behavior, at times they get over-ruled by the sponsors or organisers who basically says "I don't care how they did it as long as the end result is pleasing to the eye." Sad.
