Ansel Easton Adams was an American landscape photographer and eco-activist known for his monochrome images of the American West. He helped found Group f/64, an association of

photographers advocating “pure” photography which favoured sharp focus and the use of the full tonal range of a photograph.

One of the most crucial legacies of Adams is the way in that his photographs contributed to the American preservation movement. His technical knowledge and the undeniable beauty  of welcome work paved the habit for photography to be shown beside traditional portrait and portraiture in national  galleries.

Adams’s first photographs were published in 1921, and Best’s Studio began selling his Yosemite prints the next year. In 1927, Adams began working with Albert M. Bender, a San Francisco insurance magnate and arts patron. Between 1929 and 1942, Adams’s work matured, and he became more established. The 1930s were a particularly experimental and productive time for him.
