Ansel Adams invented the zone system, a technique which allows photographers to translate the light they see into specific densities on negatives and paper, thus giving them better control over finished photographs. Adams also pioneered the idea of visualization (which he often called 'previsualization', though he later acknowledged that term to be a redundancy) of the finished print based upon the measured light values in the scene being photographed.
Ansel Adams was a preeminent photographer and conservationist
; born in San Francisco in 1902. A commercial photographer for 30 years, he made visionary photos of western landscapes that were inspired by a boyhood trip to Yosemite. He won three Guggenheim grants to photograph the national parks (1944--58). Founding the f/64 group with Edward Weston in 1932, he developed zone exposure to get maximum tonal range from black-and-white film. Ansel Adams died in 1984.
