Renowned as America's pre-eminent black-and-white landscape photographer, Ansel Adams began to photograph in color soon after Kodachrome film was invented in the mid 1930s. He made nearly 3,500 color photographs, a small fraction of which were published for the first time in the 1993 edition of ANSEL ADAMS IN COLOR. In this newly revised and expanded edition, 20 unpublished photographs have been added. New digital scanning and printing technologies allow a more faithful representation of Adams's color photography.
