Ansel made a lot of powerful photographs, but for me, this one falls short. First, less foreground would strengthen it. Perhaps a longer lens would have been a better choice. Also, this situation calls for greater elevation, not always possible, and the reason Ansel often photographed from his roof platform. However, it's Ansel's photograph, and he was most likely pleased with the result. That is what matters.
I don't recall having seen this photograph. I knew Ansel well, and he had a large impact on my life as a photographer. I think many photographers today owe a great deal to Ansel.
Thanks for posting this photograph.
