There was an episode of one of the Huell Howser shows on KCET (the LA public television station) a few years back where he visited the Central Library and got the story of the AA pictures. I found it interesting, not so much for the images themselves, but for the insight into Adams' life at the time including his need to make money and how any of us may well excel at certain types of photography and be nothing special in others. Adams clearly knew the actual artistic value of the work, but also saw where someone else could see them as a valuable part of the narrative of Los Angeles of the time they were made.
Huell had his usual assortment if "Woooww"'s and expressions of amazement at holding an actual negative Adams had made.
Adams has become so sanctified, which I don't consider a bad thing for photography, but many folks don't realize that not everything he did was wonderful. We know only the photos he wanted seen, and the other thousands remained in his files, where they are of interest mainly to students and historians. To me, one of the laughable things about the Norsigian pictures was that even if they had been authentic, there were many thousands more "lost" photographs in his archive at the University of Arizona.
