On a blazing summer day in 1916, a teenager named Ansel Adams first encountered the awesome beauty of Yosemite Valley. "From that day," he later wrote, "my life has been colored and modulated by the great earth-gesture of the Sierra." This youthful awakening to the sublime power of the wilderness was the beginning of a lifelong journey for Adams- a quest in which he would discover the power of photography to reveal mankind's place in the natural world. His work was part of an extraordinary revolution in photography that sought to capture what Adams called "the continuous beauty of things that are," the landscape of the North American continent. More than any other artist of the twentieth century, Adams helped transform the meaning of wilderness in America; his greatest images of the American West changed forever what Americans thought about their own land.

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.
