Arthur Ou; Double Light Leak 2 (2010); Chromogenic print; 30 × 40 in.; Edition 1 of 5

This unconventional vest-pocket space continues its six-month investigation into copying versus originality. A big, glittering painting by Handelman lacks any trace of the artist’s hand—its cool, crystalline, ground-glass veneer suggests it was produced mechanically, although it was not. Rostovsky composed his paintings of flowers, and of a protester on fire (obscured by a large red rectangle), on a digital tablet and made the files available for free online: they are presented here as elegant light boxes. Ou is the show’s lone photographer yet he contributes its most painterly works: two black-and-white images in which ribbons of graffiti, sprayed onto wood and paper, twitch like live wires. Through June 9.
