That's a great review. In the show there is a card with paragraph or two about him destroying his negatives. My wife asked me why anyone would do something like that and I tried to answer as best as I could regarding the continuity of his vision and how he probably viewed his work all the way from the ground glass to the final version of the print. Mark Feeney put it much more eloquently that I did... I'll show her the article tomorrow. Bill, if you get a chance you won't be disappointed. The show is inspiring and a great opportunity to view a master's work.
