Ansel Adams

Famous for his black & white landscape photographs of the national parks (Yosemite National Park among others), and as an author of numerous books about photography, including his trilogy of technical instruction manuals (The Camera, The Negative and The Print). He co-founded the photographic association Group f/64 along with other masters like Edward Weston, Willard Van Dyke, Imogen Cunningham and others.

He invented the Zone System a technique that allows the photographer to translate a visual impression of his or her subject to photographic film and paper. As well as the Zone System, Adams also pioneered the idea of 'pre-visualisation', the idea of seeing a completed print and then working through the steps to build that print.

Adams disliked the uniformity of the education system and left school in 1915 to educate himself. He originally trained himself as a pianist, but at age fourteen was given a camera as a gift while visitng Yosemite National Park.

During his lifetime he was a member and, later, director of the Sierra Club, a group dedicated to preserving the natural world's wonders and resources. Adams' was an environmentalist, and his photographs are a record of what many of these national parks were like before human intervention and travel. His work has promoted many of the goals of the Sierra Club and brought environmental issues to light.

For environmental reasons, Ansel Adams was an advocate of Fusion Power.
