Meggan Gould, a New Mexico–based photographer, has spent eight years documenting surfaces—the more fleeting, the better. Blackboards with haphazard coatings of chalk dust, cryptic writings on the reverse side of vintage photographs, momentary arrays of digital icons on computer desktops, dirt and fuzz resting on camera viewfinders, even fingerprint smears on iPads—they’re all in Gould’s project called “Surface Tension,” excerpts of which are now on view in an exhibit at Montgomery College in Silver Spring. “I find myself continually drawn to using the still photograph to fix or freeze shifting surfaces, particularly surfaces that are rarely, if ever, considered as valid visual ‘canvases’ in and of themselves,” Gould says. While her images of dated computers and old-school blackboards suggest the relentless march of technology, Gould says she’s more interested in the visual aspects, “mutable surfaces that are constantly shifting.” The project was not without ironic discoveries: It turns out making images of camera viewfinders is a technical chore—they have to be shot in macro segments and then painstakingly stitched together. Fortunately, that diligence pays off. The exhibition is on view Mondays through Fridays 8 a.m. to 5 p.m. to Dec. 23 at the Morris and Gwendolyn Cafritz Foundation Arts Center at Montgomery College, 930 King St., Silver Spring. Free.
