Ansel Easton Adams (February 20, 1902 – April 22, 1984) was an American photographer and environmentalist best known for his black-and-white landscape photographs of the American West, especially Yosemite National Park.
With Fred Archer, Adams developed the Zone System as a way to determine proper exposure and adjust the contrast of the final print. The resulting clarity and depth characterized his photographs and the work of those to whom he taught the system. Adams primarily used large-format cameras despite their size, weight, setup time, and film cost, because their high resolution helped ensure sharpness in his images.
Adams founded the Group f/64 along with fellow photographers Willard Van Dyke and Edward Weston. Adams’s photographs are reproduced on calendars, posters, and in books, making his photographs widely distributed.
Ansel Adams’s photograph The Tetons and the Snake River has the distinction of being one of the 115 images recorded on the Voyager Golden Record aboard the Voyager spacecraft. These images were selected to convey information about humans, plants and animals, and geological features of the Earth to a possible alien civilization. These photographs eloquently mirror his favorite saying, a Gaelic mantra, which states “I know that I am one with beauty and that my comrades are one. Let our souls be mountains, Let our spirits be stars, Let our hearts be worlds.”
