This has got to be one of the best places to view photography anywhere. This non-profit museum under the bay bridge focuses each exhibition on a particular theme, drawing from the collections of its founders, Andrew and Mary Pilara, and other photo collectors. Admission is free but only by appointment, which means you have an amazingly peaceful and crowd-free viewing experience. #sanfrancisco #freeart #pier24 #embarcadero #photography #sanfranciscoart
