His images incorporate tow distinct photographic techniques: time-exposure by the natural light of a full moon, and the artful application of artificial light, vividly 'painted' into the scene while the camera's shutter is open. Nightwatch: Painting with Light is the first book from Kerns, one of the world's foremost practitioners of the art of light-painting. Join him as he ventures into the darkness of the American Southwest, exploring remote desert ghost towns under a full moon, or prowling the abandoned, seemingly post-apocalyptic structures of American's industrial wastelands. In his photographs, Kerns captures the world surreal: flowing cloud-streaks in a night sky, the laser-like light trails of cars racing by on a highway, a raging ocean shoreline rendered eerily calm through long exposure.
