Andrea G. Stillman was Ansel Adams's assistant in the 1970s. The New York Times has just posted a multimedia presentation where Ms. Stillman talks about working with Ansel, and discusses the stories behind some of his best-known photographs. She also explains why Ansel insisted in shooting in B&W when Kodak asked him to take some photgraphs on Kodachrome.
A must-see and hear!
