Ansel Adams

Ansel Easton Adams (English: Ansel Easton Adams, February 20, 1902 - April 22, 1984, also translated as Ansel Adams) was an American photographer and environmentalist born in San Francisco. He is known for his black and white landscapes, the most famous of which is the Yosemite National Park series. He also wrote on photographic subjects, such as the trilogy of technological innovations ("Camera", "Negatives" and "Prints"). In the photography community f/64, which he helped to found, masters such as Edward Weston, Willard Van Dyke, and Imogen Cunningham can be seen. He proposed the technical concept of "area system" and believed that photographers should use changes in light to control the density look and feel of negatives and photographic paper. Adams also advocated the concept of "visualization" (he also often called it "pre-visualization", but this term was not accepted by later generations), which means that the perception of a photo depends on the measurement of light, which is determined at the moment the scene is captured in the lens.
