Ansel Easton Adams (February 20, 1902 – April 22, 1984) was a 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.1
