As in many arguements with opinions on both extremes, the facts usually lie in the middle.
Winogrand was the first to admit he "was a mess" when it came to processing and editing his images for books or exhibitions. I was at his apartment in Austin helping him fix his audio system while he was working on selecting the images for
Women are Beautiful. The whole place was filled with stacks of work prints he was reviewing.
I was a student of his when Lee Friedlander came to Austin and lectured to Wingogrand's Art Photography classes. I was told later that Friedlander was really in town to prod Garry to finish the image selection of
Public Relations.
Winogrand developed by inspection, a slower, more "interactive" processing method when developing Tri-X in D76. I believe one of his trusted TAs in Austin did develop some film for him, but other than that I think he processed all his own rolls. Given his love of shooting, it is no real surprise he would never have caught up with his processing NO MATTER HOW LONG HE LIVED.
(Not to plug this too much, but I wrote an article years ago about my recollections of taking Winogrand's art classes - much of what I have said above is in that piece. I illustrated the article with some photos of Winogrand that you may not have seen before: Click on
"Class Time with Garry Winogrand")
Chris makes a point that is worth really emphasizing and that is frankly at the core of this thread: if you do not edit your work - assuming of course that there is a public demand to see your work after you assume room temperture - then someone else will edit it for you. Wingrand had no real filing system or archives - those were not his talents. He had thousands of rolls and contact sheets he never developed or reviewed. And Winogrand was first in line to blame himself when he couldn't find a negative he needed to print, for bags and bags of Tri-X, for stacks of contact sheets and sleeves full of negatives he would never see. That part of the photographic process did not rate as high on his priority list at shooting more images.
I do a short program on Winogrand for local photograpy clubs and the local college photography classes and the most common question I am asked is what Winogrand book do I like best. In my opinion, any of the books that Winogrand took part in the image selection are more "Winogrand" than those published after his death. The images seem more consistent. Hence, back to Chris's point asked in a different way - would Winogrand agree with the images selected for the books and exhibitions since his passing?
We will never know ...
