rarindra prakarsa, while having obviously heavily processed pictures, does it in a natural manner. i would not really lump him together with the latter group that you have mentioned, because they have massive haloing, etc.
i am frankly, disturbed by the proliferation of the 2 extremities, people who are so bloody proud about how "they have no pp" when it is obvious that the picture needs basic pp, like correction of tilt, vertical perspective correction etc to make it look more aesthetically pleasing (azure is different, his are already solid out of cam at those sizes so i am not attacking him, note).
then you have those who pump their pictures into some mutant machine, and it comes out looking like a gremlin from hell, and they will stick to their guns despite how many people tell them that it looks like a gremlin from hell, under the shield called "artistic license"
sure, PP ALL YOU WANT
but when it looks bad, smells bad, tastes bad, it's bad, no matter how much you want to say that you are entitled to producing bad stuff. i suppose you are, after all
i can give so many examples of people who pp heavily but still are received widely. besides your earlier example, dave hill is another, angelreich on deviantart
here is another
extreme pp is not the problem
it's the eyesoreness that is the problem, i hope we all get that clear, so there is no need to hide behind any pp shields
and i think we should all be frank, sugar coating it and being nice and diplomatic, often does not work, because well, welcome to clubsnap these days
