Zone System

The zone system was invented by Ansel Adams which is one of the most famous photographers ever. The zone system is very simple and its principles are logical and easy to understand. Its scientific basis had been known long before Ansel Adams and Fred Archer hit upon the method in the 1940s.The zone system is made up of three basic components which were very important to Ansel Adams. They are visualization, exposure control, and contrast control. The difficult terms of zone are Visualization, exposure, and contrast controls are terms that are simple to understand. What can be confusing are the words Ansel Adams used to describe exposure and contrast control: Zone V or Zone III exposure, N-2 or N+1 development. The Brightness levels are a common mistake to think that you only take one exposure each time you press the shutter button. You take an exposure with a specific aperture and at a specific speed. The photographic film reacts to exposure. When film is developed, the blackness increases to a large extent in proportion to the exposure. A strong exposure (a white surface in sunlight) means that development heavily darkens the negative. An Ideal exposure film is going to be exposed in a camera; we have to make sure that the entire object’s individual exposure values fall within the film’s exposure latitude.
