Perspectives by Dennis O’Keefe Perspectives: A Photography Exhibition Photoworks Gallery and Photography School in historic Glen Echo Park presents Perspectives: A Photography Exhibition by Dennis O'Keefe and Sarah Hood Salomon where abstract art and photography intersect. The show runs June 14-July 22. Salomon, a photographer and writer living in Bethesda, uses camera motion and slow shutter speeds in order to compress transitional qualities of light into one image. By moving the camera while the shutter is open, light is formed into specific 'brush strokes.' Gallery hours are Saturdays, 1-4 p.m. and Sundays, 1-8 p.m. Photoworks Gallery and Photography School at Glen Echo Park, 7300 MacArthur Boulevard, Glen Echo. Visit www.glenechophotoworks.org.
