Abstract
A method of automatically controlling exposure when printing from film which is exposed under controlled lighting conditions. The prevailing lighting conditions are determined by photographing a standard subject in the form of a gray-scale board with at least one field of gray and illuminated by the studio lighting. The gray scale is recognized as a standard subject during region-by-region analysis of the film's frames and the results obtained from the gray scale are employed as a film-specific standard in computing the levels of light to use for printing.
