Near black, with slight tonality but no texture II Textured black; the darkest part of the image in which slight detail is recorded III Average dark materials and low values showing adequate texture IV Average dark foliage, dark stone, or landscape shadows V Middle gray: This is a rule of thumb. Some film stocks have steeper curves than others, and the cinematographer needs to know how each one handles all shades of black-to-white.

The zone system provides photographers with a systematic method of precisely defining the relationship between the way they see the photographic subject and the results they achieve in their finished works. In a sense, the zone system plays the same role that color management does for digital photographers.

It allows for a direct correlation between the visual world and the final photographic print. Misconceptions Unfortunately, the zone system gained an early reputation for being overly complex, difficult to understand and impractical to apply to real-life shooting situations. Two facts account for this misunderstanding: Also, the zone system was initially designed for use with large format cameras where individual sheets of film could be processed separately.

This allowed photographers to apply the zone system method to each subject discreetly, which is an ideal approach not easily applied to roll film cameras that, until the digital revolution, dominated photographic practice.

One other misconception about the zone system is that it does not apply to color or digital photography. In fact, the zone system is conceptually extremely simple and because of certain limitations inherent to traditional and digital photographic materials, any photographer who achieves consistent quality in their work has to be using some variation of the zone system whether they are aware of this or not.

Dynamic range What makes the conceptual basis of the zone system necessary is the fact that modern photographic papers and current digital light sensors are very limited in the range of tonal values they can render.

If you were to double in steps the amount of brightness you used to expose photographic papers, depending on the grade of paper or variable contrast filtration you are using, you can only go between 6 to 12 steps or stops before the paper would stop recording any difference between one stop and another.

Another way of saying this is that the dynamic range of photographic papers is limited to a ratio of very roughly 1 to It is interesting to note that in the earliest days of photography, printing papers had much longer scales.

The trade off is that they were also much less responsive to light.

On the other hand, through a complex process of biochemical adaptation and our pupils adjusting, the human eye can perceive an extremely wide range of tones from the darkest value we can see, to the brightest light we can tolerate.

The dynamic range of the human eye can be 1 to 1, This means that photographers must bridge this gap through a method that allows for the final prints to approximate the way the world looks to our eyes. The zone system does this by providing photographers with a simple way to control the contrast of the film negatives in their cameras.

Principles Contrast control of this kind is made possible by the fact that the amount of exposure the film receives has its primary effect on the darker parts of the photographic subject.

The amount of time that film is developed controls the density of the lighter parts of the subject. This classic rule was stated in this way: By first properly exposing their film, and then either increasing or decreasing their film development times, zone system photographers can, within limits, produce negatives that will print beautifully, regardless of how contrasty or flat the original subject happened to be.

Careful and committed photographers came to understand the above-described principles through the process of trial and error long before the zone system was formulated. The real genius and contribution of Ansel Adams and Fred Archer was creating a way for photographers to easily translate the range of tones they could see into a visual ruler that could be used to measure various subject tonal ranges in a predictable and practical way.

Measuring Zones Zones represent amounts of light that double as the zones become lighter and halve as they get darker. In this sense, zones are equivalent to all other photographic controls.Fred R. Archer (December 3, – April 27, ), was an American photographer who collaborated with Ansel Adams to create the Zone System.

He was a portrait photographer, specializing early in his career in portraits of Hollywood movie stars. The Zone System is an exposure metering system invented by Ansel Adams and Fred Archer () It explains exposure of varying luminance in an image. Why did Ansel Adams prefer pictures in black and white over color?
