Of all the photographers on this list, Ansel Adams is perhaps the most widely recognized, and for a good reason. His photographs of the American West, particularly Yosemite National Park, are iconic and beloved. In addition to his impressive body of work, Ansel Adams left his mark on photography by developing the Zone System. This system was a way to determine proper exposure and contrast in the final print, and it resulted in intense clarity and depth, as evidenced by his photographs. His intense commitment to quality is inspiring to photography students.
