I’m reading John Richardson’s Picasso biography right now, volume 2, 1909 – 11, the ‘discovery’ of cubism. I like his assertion that cubism opened the doors for much of the other innovation that was to take place subsequently in the twentieth century. And, of course, being a photographer, I’m thinking about and looking for similar sorts of dynamics that, in one way or an other, break away from the built in realism of the medium — both the physics of it and the psychological/social stances.
