Ansel Easton Adams (February 20, 1902 – April 22, 1984) was an American landscape photographer and environmentalist known for his black-and-white images of the American West. He helped found Group f/64, an association of photographers advocating "pure" photography which favored sharp focus and the use of the full tonal range of a photograph. He and Fred Archer developed a system of image-making called the Zone System, a method of achieving a desired final print through a technical understanding of how the tonal range of an image is the result of choices made in exposure, negative development, and printing. One of the most influential photographers of the 20th century along with other photographers of his time such as: Man Ray, Edward Weston, Henri Cartier-Bresson, Robert Capa, Elliott Erwitt, Walter Evans, Philippe Halsman, Diane Arbus, Eve Arnold, Robert Doisneau, Josef Sudek, Robert Mapplethorpe, Steve McCurry, among many others.
