Sue de Beer’s moody photographs of twentysomethings bathed in tinted light set the stage for this meditation on classic themes of youth and beauty. Smaller pieces can look a bit lost in this town-house gallery’s high-ceilinged rooms, lending the show a sense of isolation, alienation, and drift. Subjects close their eyes or turn away from the camera in pictures by Jeff Burton, Dorothee Smith, and Viviane Sassen. In works by Annika Larsson, Eva Stenram, and Eric Stephany,figures appear fragmented and ephemeral: a bare leg, a clenched palm, a shadow. Keith Edmier’s gorgeously surreal flower sculptures, including a funeral wreath, add an appropriately elegiac note. Through Dec. 20.
