In photography, the march of technology goes on, but black-and-white imagery never loses its authority. At least it would seem so, looking at David Myers and Harvey Kupferberg’s show at Glen Echo’s PhotoWorks Gallery. In 2008, Myers lovingly documented the City of the Dead, a burial site in Cairo that’s also home to hundreds of thousands of the city’s living poor. Myers’ images skew placid: a bird taking flight in a peaceful courtyard, close-ups of gravestones and marble tomb carvings, and a man, cut off at the shoulders, carefully fingering an old, leatherbound volume—an image that must have required deep trust to make. Meanwhile, Kupferberg chronicles the American Southwest and adds some pleasant twists. He not only captures the mesmerizing swirls of canyon walls but also the delicate flaking of rock towering over a small, ancient stone structure (shown). Particularly striking is an image of vegetation-pocked sand dunes; the plants cast long shadows, including one that resembles a brushstroke. A painted desert indeed.

The exhibit is on view Mondays and Sundays 1 p.m. to 8 p.m., Saturdays 1 p.m. to 4 p.m., and any time a class is underway through Jan. 7 at Glen Echo PhotoWorks, 7300 MacArthur Blvd., Glen Echo. Free. (301) 634-2274. glenechophotoworks.org.
