Depth of field depends primarily on camera-to-subject distance, aperture, and focal length. As such, to obtain photographs in which all parts of the model are in focus, you need to obtain the maximum depth of field for the given aesthetic constraints. The aesthetic value of the photograph depends primarily on the vantage point, the perspective, and the lighting. You obtain the combined effects of vantage point and perspective by selecting the camera-to-subject distance and the corresponding focal length of the lens. You determine the lighting by moving the lights from position to position until you achieve the desired effect. However, you need to obtain lighting that is intensive enough to avoid excessively long exposure times.

Thus, generally speaking, these factors require that you mount the camera on a tripod and that you use small apertures and slow shutter speeds, e. g., ½ sec or 1 sec. In addition, for SLR cameras, to avoid camera shake, you need to move the mirror manually out of the light path prior to releasing the shutter and subsequently to release the shutter using a "cable release." Alternatively, a simpler approach is to release the shutter using the self-timer, which performs the same function.

If you are using film, you should use a slow film speed, e. g., ISO 100. If you are using a digital camera, you should select the slowest "film speed."

If you are photographing models that have no particular color scheme, black-and-white is the preferred medium. You may use "chromogenic" film that gives black-and-white negatives. This type of film is actually a color emulsion that can be processed using commercial color-processing machines, i. e., it can be processed using the C-41 process.

If you use color negative film, you can purchase film that is balanced for "tungsten" light, i. e., light corresponding to a color temperature of 3,200 K. Alternatively, you can use color film balanced for daylight and an 80a color-correction filter.

For this type of assignment, you should record the technical information for each frame, so that later you can determine which conditions correspond to which picture. For example, you can create a table that consists of 36 rows, each corresponding to a frame on a roll of film. The table consists of several columns labelled: frame number, model, focal length, exposure, and lighting.

Select two models to photograph, which may be your own models and which differ in size and shape. For example, you may choose a model that is roughly square in length and width and a model that is long and narrow.

For each model, record photographs from at least two vantage points, which include eye-level and bird’s-eye views. For a selected view, maintain the same lighting but record the photographs using both a wide-angle and a telephoto lens. For a selected view, use two different types of lighting.

Thus, for each model, you will submit four nominally 8- x 10-inch or 8- x 12-inch enlargements (or more if you choose). Follow the technical guidelines given in earlier assignments.

Although the final product consists of four photographs for each model, you should vary the conditions and record correspondingly many photographs. From this set, you should select the best images for subsequent enlargement.

With the photographs, submit a brief statement in which you present the technical details:
