I visited the museum yesterday. A very good exhibit; about 1/2 devoted to the cameras and 1/2 to photographs using Polaroid film. Most of the photos were just OK (IMO). Not enough of the 20x24 Elsa Dorfman ones. One thing I did not realize was the extent of the collaboration between Edwin Land and Ansel Adams. I knew Adams used Polaroid film, but not that he was so involved in it's refinement.
