TO OCT. 14

The 14 photographs at the Kathleen Ewing Gallery that comprise The Landscape: An Exhibition of New Photographs come from seven states and one Canadian province. Yet each image, created through the lens of Washington photographer Frank DiPerna, coheres to a unified aesthetic: horizontal arrangements of washed-out baby blues and beiges. Typical of DiPerna’s empty, near-abstract vision is “The Cut, Southampton, New York,” which records the meeting of land and sky, separated only by a tiny resting seagull and an exceedingly thin hint of waves. The main variation from image to image comes from the textures: The beiges originate from grass, sand, gravel and dirt, while the blue sky comes shrouded in a variety of cloud formations. The variations from this dominant theme are so rare that when they appear, they’re striking: sandwiched layers of red dirt and green grass in a landscape from Nova Scotia, or a bold stripe of Mediterranean-blue ocean off Nantucket. DiPerna’s eye is keen and his vision is strong, but if you’re seeking more traditional landscapes, flip instead through a binder of photographs taken by Christopher Burkett, which happens to be sitting on a table in the middle of the gallery. Showing simultaneously at the Ewing is Livestock: An Exhibition of Paintings and Drawings, which features renderings of sheep, cows, and goats by Roberta Marovelli, DiPerna’s wife. Through Oct. 14 at the Kathleen Ewing Gallery, 1609 Connecticut Ave. NW. Free. (202) 328-0955. (Louis Jacobson)
