Looking back it is amazing to see the effort that photographers used to go to just to get a single shot. Ansel Adams was known to “pre-visualize” an image and then to go back to the same location, day after day until the light was just the way he wanted it. He would set up his camera many times but never take a shot if conditions were not right. After that he would shoot a few frames and the rest of his magic was done in the darkroom.
Ansel Easton Adams (February 20, 1902 – April 22, 1984) 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 in books. He along with Fred Archer, developed the “Zone System” of exposure to improve the detail and optimum contrast in his images.
