Ansel Easton Adams was an American photographer and environmentalist. His black-and-white landscape photographs of the American West, especially Yosemite National Park, have been widely reproduced on calendars, posters, and books. In the magic of the place and moment he conveys universal experience. A fine craftsman employs different tools for different purposes. It has been written of him that his pictures are all the more precious because they stand as the last records for the young of what they missed and for the aging—for a little while—will be a souvenir of what was lost.
