Ken is clearly very experienced, talented, and opinionated. He's great at what he does, from everything I've looked at. For that, he's entitled to be opinionated, to me. Do good work and your opinions about that work become important.

Having said that, I found this bit on Ken's Why Your Camera Does Not Matter page that was rather irksome. Quoth Ken:

*sigh*

If you're not copying Ansel or Jack's photos, you're not infringing on their copyright. It may be repugnant, from a 'common decency' perspective, for someone to make photos that are inspired by, or even emulating, the style of another photographer, but it's not copyright infringement unless the original work is copied. The copyrighted work isn't the scene being depicted-- it's the photographic image.

Ken's opinion confuses me. He seems to exude a very "go out there and take some pictures" attitude throughout most of his site, but then he goes off and says things like the above. All art is derivative, and all artists get their inspiration from somewhere. It may be amateurish, even gauche, to draw so directly from the body of work of another photographer, but it's hardly copyright infringement.
