Gurujeet Khalsa of Chevy Chase, Md., has a career in technology, but he’s an aficionado of Japanese gardens and the board game Go. He’s also a photographer, and not a bad one. His exhibit at Glen Echo Photoworks includes works from all over, most of them focused on the natural world. A number of Khalsa’s photographs echo the signature out-of-focus vegetation images of Terri Weifenbach—not surprising, since he studied with her. One image focuses on the delicate hairs on a spindly branch and another contrasts a thicket of boughs with a disorienting sand backdrop (pictured). Khalsa’s most visually pleasing images are his simplest. In “Capitol Crescent #1,” he photographs red, chalky nuggets scattered on a surface of gravel, suggesting some of the more contemplative works of Gabriel Orozco and Andy Goldsworthy. “Rock Creek Cemetery” features an oddly absorbing sprinkling of red, green, and black detritus on a layer of pure white snow, looking like flecks resting gently on a scoop of vanilla ice cream. The results are equally sweet. The exhibition is on view 1 p.m. to 8 p.m. Sundays and Mondays, 1 p.m. to 4 p.m. Saturdays, and whenever a class is in session at Glen Echo Photoworks, 7300 MacArthur Blvd., Glen Echo. Free.
