Portrait photographer Elsa Dorfman found her medium in 1980: the larger-than-life Polaroid Land 20”x24” camera, one of only a handful in the world. In the ensuing 35 years she’s taken approximately 4,000 photos, masterfully capturing the “surfaces” of those who visited her Cambridge, Massachusetts studio: Beat poets, rock stars, Harvard notables and families large and small—from complete unknowns to legends like Allen Ginsberg, Lawrence Ferlinghetti, Jorge Luis Borges, Jonathan Richman, Joni Mitchell and Bob Dylan. Her generosity of spirit and love of her fellow humans make her a great portraitist, and her photographs reflect her joyful spirit. But the film stock she uses is no longer made by Polaroid, who declared bankruptcy, hastening her looming retirement. Looking back on her rich career, Dorfman gives longtime friend and Academy Award-winning filmmaker Errol Morris (The Thin Blue Line, A Brief History of Time, The Fog of War) an inside tour of her backyard archive, including the beloved photos she calls the rejected “B-sides”—images turned down by her subjects but often better than the ones they’ve chosen to keep.
