Lee, I was also there..waited in line to get in, then managed to get the book signed and get out. The slide show/Q&A was really quite fun. You are correct, wish I had that much energy now - Avedon is full of energy, HE BELIEVES IN HIMSELF, and is VERY SURE of what is doing. One note - it was all about the image - not so much the technical part, that is learned and applied, but working with the subject until they were comfortable. Well worth hanging around after work.
