“One of the most telling images in the Museum of Modern Art’s beautiful but demanding survey of the Conceptual photographer Christopher Williams represents an act of elegant iconoclasm. It lays bare something most of us rarely see: the guts of a camera’s lens. It is an amazing sight....He is an ardently self-conscious artist who wants to let us in on his entire act. You feel his touch everywhere....There’s nothing that he hasn’t tweaked....All these details conspire to make us look harder, and the images feel a little like windows, an expansive effect.” —Roberta Smith, The New York Times
