I haven't taken a great, investigative interest: I have seen some of it here and there (not as print) and it only says manipulation skills to me. That isn't what photography, to me, is all about. I simply don't see the point of juxtaposing all manner of things that make little or no logical sense (to me) at all. Because one can doesn't mean that one should. I have no doubts as to his skills, only their application.
In photography, I really do believe in the notion that simplicity means more focussed thought rather than contrived thought. No, I'm not saying that a shot of a blank sky says more than WYSIWYG!
I don't necessarily disagree with the simplicity stance, well done simple images usually are quite strong. However, when I look at manipulated images they aren't really much different to me than paintings with a strange concept, or a book like Lord of the Rings with creatures that don't and have never existed, or a science fiction movie that breaks every physics law we know. It doesn't have to reflect reality to be enjoyable, just needs to be done well.
