Three-Color Subtractive Photography
The color-vision characteristics of the eye are discussed and the rules which are followed are used to show the requirements for the “perfect” additive and subtractive three-color photographic processes. Since these requirements are not achieved in practice, a theoretical study of a practical color process may not always give an adequate analysis of its usefulness. However, such an analysis may point out some of the pitfalls which occur in practice. For example, many subjects may appear to be the same color to the normal eye and yet give different results when photographed. Also, any given color may be reproduced incorrectly by any process in use. — The effects on picture quality of changes in contrast, balance, and a variety of other variables are shown. The restrictions which some of these factors place on the use of color films are mentioned.
