To this outsider this is true. John Szarkowski was a conspicuous example. His own photographs are bland. His comments in Ric Burns' film on Ansel Adams were superficial when compared to the more knowledgeable contributors in the earlier Ansel Adams film directed by John Huszar. His Looking at Photographs: 100 Pictures from the Collection of the Museum of Modern Art smells more like an attempt to justify some acquisitions of his museum rather than a perceptive analysis. Perhaps I would enjoy some of his other books more, but time spent on this site is more productive.
