I happened to be in Washington, D.C. at the same time FotoWeek was happening. I visited the main exhibition space - two floors of a former Borders location - featuring selected prints from photographers around the world. There were amazing photos in multiple categories: environmental, street photography, documentary, landscape, nature, wildlife, etc. Concurrent with FotoWeek the Corcoran Gallery of Art sponsored lectures and an exhibit of Gordon Parks' photographs from their collection. The Gordon Parks exhibit continues through January 16, 2012. At the National Gallery of Art a retrospective of Harry Callahan's work, "Harry Callahan at 100" includes an early experiment capturing a flashlight on film in a dark room (or outdoors?). His color work features neon signs and camera movements - similar to what many people are doing today, decades later. "Harry Callahan at 100" is on view through March 4, 2012.
