I think thats going a little too far. you cant prove its been touched up without sending the raw file in and there is no way I am giving my raw files to anyone as if you have access to the raw file then you basically have ownership of the image. Also what if people use an SLR and shoot in JPG (I think Chinky C does)
The competition is not about who is the photographer its about the best photo. If you think it looks over edited and that ruins it for you a bit then don’t vote for it
