Avid art photographers will learn how to model their work after legendary black-and-white photographer Ansel Adams in this instructional guide. Adams’ methodology, known as the Zone System, takes what the viewer will see—the final print—into consideration at the beginning of the photographic process, rather than focusing strictly on what the photographer sees. Once this concept, called “previsualization,” is presented and defined, the book then follows a step-by-step approach to incorporating these ideas into all aspects of the photographic process, including lighting, exposure, development or digital editing, and printmaking or output of digital images. Whether working in film or digital media, these steps will foster early accuracy and elicit better source material from a camera, which allows for greater control and contrast in the lab or on a printer.

amount of light from the film that will fit within the range of the paper. If we then change the angle (slope) of the film curve, we can see that less or more of the scenic flare curve is useable as we move horizontally from the intersection points of the vertical lines from the paper and the new film curve. This diagram shows how the increase in development affects the characteristic curve. The red line indicates the normal development and the shaded area under the curve represents the

there will be less shadow detail than with normal development, and the opposite is true with overdevelopment. For this reason we need to establish a method for adjusting the exposure, and using different ISO settings in the metering system depending on the SBR is an excellent approach. Calculating effective ISOs for various developments can be done with the same testing materials and on the same set of characteristic curves already The graph shows the relationship between the exposure index

these two areas for normal, with two stops in between. For studio work, photographers often rely on an incident-type flash meter. Though we control the light in the studio, we can still use the Zone System. Reading the light ratio, which describes the relationship between the main light and fill light, can allow us to employ the overall approach to the Zone System. We point the dome of the meter at the main light to obtain our first reading, then point it at the fill light to establish its value.

absorption and interference filters, are used to increase or decrease the contrast that will be created during exposure. This can change contrast relationships between varying subjects within a single image. (Note that another group of filters, special effects filters, do not affect image contrast.) First are absorption filters. These reduce the amount of light that is transmitted to the film by absorbing part of the light reflecting from the scene. The simplest type to understand are the neutral

changes, we produced all Zone I exposures. This zone concept will be covered in chapter 3.) Develop the film using your standard development method and time. The resulting strip of film will have two blank frames at the beginning, then a series of frames starting relatively thin and fading to no density. Once the film has dried, read the negatives with a densitometer. (The following instructions will assume you’re using ISO 100 film. If you’re using some other ISO, your results will be similar
