the family is disputing these claims: http://theanseladamsgallery.blogspot.com/2010/07/response-to-july-27-2010-article.html
Interesting. Besides, I was wondering about that, because....Ansel's magic happened in the darkroom, not in the field.
The blog post from the family is pretty interesting. ; Hopefully the guy who bought the negatives will do more testing and come to a more solid conclusion.
Another update: http://www.ktvu.com/news/24432262/detail.html A woman thinks the negatives are the work of "Uncle Earl".
Update: ; the Ansel Adams Trust is suing the guy who owns the negatives to force him to stop using the Ansel Adams name on all prints not authorized by the trust: http://www.foxnews.com/us/2010/08/23/ansel-adams-trust-sues-calif-man-negatives-purported-photographers-lost-work/
