Biography provided by Focal press
 
Through his writings, environmental activism, and photographs, Adams's images are seen as the quintessential pictorial expression of the American Western landscape, a site of inspiration and redemptive power to be preserved. Adams' visual power came from an awareness of light's changing nature and its movement within the landscape. With the help of Fred Archer (1888-1963), he developed the Zone System in the late 1930s, adopting the science of sensitometry to a system of tonal visualization of the image. Adams compared the negative to a musical score and the print to its performance. Images like Moonrise, Hernandez, New Mexico (1941) utilized the straight photographic precepts of Group/64 not to simply document, but to convey a transcendental sense of optimism about the vanishing pristine space of the American West. His book, Born Free and Equal (1944), testifies to the World War II internment of Japanese Americans. By the 1960s, the accessibility of Adams' images, the respect for his technical brilliance, and the ability of his work to command higher prices helped photography reach a broader range of venues.

Ansel Adams is well-known for his portrayal of the mountain ranges, deserts, rivers and skies of the western United States. Adams was a passionate lover of the vast American wilderness and an active conservationist. He commented, "my approach to photography is based on my belief in the vigour and values of the world of nature - in the aspects of grandeur and of the minutiae all about us." Having trained as a pianist before turning to photography in 1927, Adams often discussed his process of composition in musical terms.

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. Adams was a life-long advocate for environmental conservation, and his photographic practice was deeply entwined with this advocacy. At age 14, he was given his first camera during his first visit to Yosemite National Park. He developed his early photographic work as a member of the Sierra Club. He was later contracted with the United States Department of the Interior to make photographs of national parks. For his work and his persistent advocacy, which helped expand the National Park system, he was awarded the Presidential Medal of Freedom in 1980. In the founding and establishment of the photography department at the Museum of Modern Art in New York, an important landmark in securing photography's institutional legitimacy, Adams was a key advisor. He assisted the staging of that department's first photography exhibition, helped to found the photography magazine Aperture, and co-founded the Center for Creative Photography at the University of Arizona.
