From the day that 14-year-old Ansel Adams first saw the transcendent beauty of Yosemite Valley, his life was, in his words, "colored and modulated by the great earth-gesture of the Sierra." Few American photographers have reached a wider audience than Adams, and none has had more impact on how Americans grasp the majesty of their continent.American Experience presents Ansel Adams: A Documentary Film, written and directed by Ric Burns and co-produced by Sierra Club Productions and Steeplechase Films. For the centennial of the artist's birth, Burns has created an elegant, moving, and lyrical portrait of this quintessentially American photographer. The documentary weaves together archival footage, photographic images, dramatic readings of the artist's own writing, and interviews with leading photographers, historians, curators, naturalists, as well as Adams's family, friends, and colleagues, to tell the story of a man who was at once a visionary photographer, a pioneer in photographic technique, and an ardent crusader for the cause of environmentalism.
