Photography’s ascent in the art world is an international phenomenon. This star-studded exhibition spans the historical roots of the medium (Ansel Adams and his generation) and the thrilling, large-format color works of such Contemporary masters as Laurie Simmons, Thomas Struth, James Casebere and Gregory Crewdson. From the documentary to the painterly, images bear witness to the times. As Susan Sontag wrote, “Life is not about significant details, illuminated a flash, fixed forever. Photographs are.”
