Ansel Adams
2/2/1902-4/22/1984
Adams is known for the idea of visualization (which he often called "previsualization") wheere his final image is 'seen" in his minds eye before he stakes a photo. His goal was to achieve his aesthetic, intellectual, spiritual and mechanical effects that he desired.
He wanted to elevate photography to an art that would be comparable to painting and music but was also as capable in expressing emotion and beauty. He said, "It is easy to take a photograph, but it is harder to make a masterpiece in photography than in any other art medium."
He carried around a pocket book called, "Towards Democracy" which he ended up taking his philosophy from, ""I believe in beauty. I believe in stones and water, air and soil, people and their future and their fate."
