I think this interview with Joao Silva, a war photographer who was recently injured by a mine in Afghanistan, is interesting. You may also find it interesting. This is a whole other aspect of photography that is beyond my comprehension.

Also, on another tact, NPR has published some street images by Ansel Adams that are very different from his usual images.
