Capturing ramshackle housing, expanses of water, flora, and urban constructions with long exposures, Callaghan conjures an eerie, atmospheric quality in the Filipino landscape, employing the simple formal and technical gestures of his medium to expressive effects. Omitting human figures in his compositions, he focuses in on the spaces between buildings or the dappled light of leaves on a brick wall, framing these elements in closely cropped compositions that render the familiar abstract. Through Callaghan’s manipulation of the photograph’s formal elements, creating sharp distinctions between colors and lines, or conversely blurring them, the images achieve a powerfully resonant quality. -Artsy.net
