Its interesting to note, that the photo.net 'unmanipulated' category, which it states has a 'very strict' definition, is in some cases less restrictive than the rules for dpchallenge - noteably that selective dodging and burning is not considered to be manipulation, just normal photo finishing as is the use of the clone and airbrush tools to remove spots or dust, as long as the original photographic intent remains.
interesting how some of photonet's 'unmanipulated' image rules are less strict than DPC's and some more.
for example, they allow cloning out dust, and selective lightening/darkening (ala dodge and burn) but they don't allow toning or selective desaturation.
I should have put a copyright on my post and gotten it registered - I could have been rich I tell you... Funnier still because I've posted the original article at least twice to other threads in the forums in the last couple of weeks....
I agree with just about everything in that article except the contention that the "real world has no grain." I believe the work of Planck, Einstein, Heisenberg, et al. demonstrated otherwise ....
