Just watched a Tivo'd copy of the American masters show on our local public broadcasting station. If you get a chance to see it, check it out. It is a great documentary about the career of Anne Leibovitz.
I have to admit, it is not my style of photography, I do not aspire to be a creater of a scene, just a recorder of a scene. I always found her stuff to be contrived, maybe a little camp some times, but after seeing a cross section of her work as she learned and expanded and went in new directions as they became available, I have to say I am very impressed by her as a human, and now as a photographer.
Anyway, check it out if it rebroadcasts in your area. A definite must see for anyone that wants to grow and learn.
