Our histogram shows 256 shades of gray. Besides pure black and pure white Ansel Adams used only nine shades to manipulate the contrast in his famous landscape photos. His zone-system can still be used for our modern digital photography.
Every landscape photographer has heard about Ansel Adams or will eventually come across that name. The famous American is mostly known for his black and white photos of Yosemite National Park. The 1941 photo Moonrise, Hernandez, New Mexico is probably his best-known photo.
One of the reasons why Adams is seen as a great photographer is because of his famous zone-system. With this system Adams was able to perfectly control the contrast in his black and white photos. Adams base rule was: “Expose for the shadows; develop for the highlights.”
Interesting to read such type of information
