Color Balance and Density Variations of Color Films Intended for Television

D. M. Zwick

Measurements on a large number of films made for television broadcasting permit quantitative statements concerning the densities of film reproductions of white objects, of black objects and of flesh. Good picture quality is associated with films having the density of important white areas between 0.30 and 0.40. The density of significant black areas of good quality film centers around 2.5. Color density measurements of flesh reproduction form the basis for a quantitative description of the color variability of motion-picture films. Color balance and density of 35mm program films match the SMPTE Reference Test Films very well; 16mm prints are measurably colder in balance. Commercials are generally lighter and colder than program material, and their variation is much greater. Newsfilm is usually greener than program film, but its variation is surprisingly small, being mostly along the illuminant axis.
