Portrait photographer Elsa Dorfman found her medium in 1980:
the larger-than-life Polaroid Land 20x24 camera. For the next thirty-five years
she captured the "surfaces" of those who visited her Cambridge,
Massachusetts studio: families, Beat poets, rock stars, and Harvard notables.
As pictures begin to fade and her retirement looms, Dorfman gives Errol Morris
an inside tour of her backyard archive.
