Ansel Adams was an American landscape photographer and environmentalist known for his black and white images of the American West. He is also perhaps the most widely known and beloved photographer in the history of the United States; the popularity of his work has only increased since his death. Adams’s most important work was devoted to what was or appeared to be the country’s remaining fragments of untouched wilderness, especially in national parks and other protected areas of the American West. He was also a vigorous and outspoken leader of the conservation movement.
The Zone System
The 11 zones in Ansel Adams’ system were defined to represent the gradation of all the different tonal values you would see in a black and white print, with zone 5 being middle grey, zone 0 being pure black, with no detail, and zone 10 being pure white, with no detail.
Visualisation
Ansel Adams describes it as the ability to see the scene you photograph and recreate in your mind the print you will produce. Meaning see your developed image, relying on the information you receive from the scene and on your developing intentions.
