This exhibition of approximately 250 photographs celebrates Robert Adams' mastery in recording the changing appearance as well as the enduring qualities of the American landscape. The confrontation between cultural remembrances of the ideal landscape and the realities of suburban expansion create beautiful, provocative photographs. His images of prairies and foothills, tract houses and mobile homes do not encourage judgments, but suggest an uneasy coexistence. Aperture, the non-profit publishing foundation, will produce an accompanying 176-page catalogue with facsimile reproductions of 130 of the finest prints in the exhibition.
