Research Collections

In addition to its fine art collections, the California Museum of Photography holds extensive archival collections including the Keystone-Mast Collection, which is comprised of over 250,000 original stereoscopic negatives and 100,000 photographic prints. The original glass and film negatives form a vital primary record of worldwide social, cultural, industrial, agricultural historicity between 1860 and 1950. Several negative archives include 7,000 by Ansel Adams from the Sweeney/Rubin Ansel Adams Fiat Lux Collection, 500 architectural photographs by Robert Cleveland, and 15,000 negatives by Los Angeles photographer, teacher and critic Will Connell.
