TO NOV. 10

In the title of her current exhibition of photographs, “Rivers and Reflections: Potomac to the Nile,” Washington photographer Claire Flanders suggests a clear linkage between the two famous rivers. But her use of different printing techniques means that her portrayals of those two rivers (A Boat in Winter is pictured) are strikingly divergent. Flanders prints her images of the Potomac (and of Cape Cod’s Pamet River and France’s Eure River) in cool, moody, selenium tones, yet she produces her Nile photographs using a warm sepia reminiscent of the salted-paper prints made by the 19th-century explorer-photographers who chronicled Egypt. Except for an excessively showy mirror-image combination print, Flanders’ cool-toned photographs are polished and smart, if not exactly groundbreaking in subject matter. Several of her sepia Nile images, however, are flat-out arresting: a fascinating, arrowhead-shaped fruit drooping from a tree, an old boat with raggedly peeling paint, and a stunning, minimalist arrangement of angles at the pyramids of Gîza. Also on display at the Troyer Gallery are works by painter Carole Bolsey of Harwood, Md. Bolsey paints distinctive oil-on-canvas waterscapes and sketchlike renderings of buildings, but the five Iris prints on display can’t quite match the power of the show’s sole original oil, Thevenin’s Barn. That work features thick impastos, a Diebenkorn-like array of diagonals, and a rich color scheme of midnight blue and mustard yellow. With both Flanders and Bolsey, it appears, the older the technique, the better. The exhibits are on view from 11 a.m. to 5 p.m. Tuesday to Saturday, to Saturday, Nov. 10, at Troyer Gallery, 1710 Connecticut Ave. NW. Free. (202) 328-7189. (Louis Jacobson)
