Photographer Van de Roer’s Portrait Machine Project show some indie- and arty-famous folk with a “controversial new-age” AuraCam trinket. Is this “biofeedback” for real? Is Miranda July mystical? Is Terrence Koh tenacious? Whatever. Aren’t the photos pretty? Aura portraiture is so the next spirit photography. “The Portrait Machine Project,” Carlo Van de Roer, Apr 16 – May 14, M + B Gallery, Los Angeles
