DOWNTOWN. A major addition to the arts complex at the University of Arizona, the Center for Creative Photography was conceived by Ansel Adams and is now the chief repository for his work. The photograph collection of the Center is one of the finest and largest in the world, with more than 60,000 photographs. Although the collection's main strength is photography by 20th-century American and Mexican artists, the Center holds significant collections of 19th and 20th century photography from around the world. In addition to Ansel Adams, the Center also contains the works of Richard Avedon, Edward Weston and Louise Dahl-Wolfe. A unique feature of the Center is print viewing. The public can view up to three boxes of prints from several thousand photographers by calling for reservations.
