Ansel Easton Adams (February 20, 1902 – April 22, 1984) was an American photographer and environmentalist, best known for his black-and-white photographs of the American West and primarily Yosemite National Park.
For his images, he developed the zone system, a way to determine proper exposure and adjust the contrast of the final print. The resulting clarity and depth characterized his photographs. Although his large-format view cameras were difficult to use because of their size, weight, setup time, and film cost, their high resolution ensured sharpness in his images.
