An exposure of a color film is scanned at a multiplicity of points in each of the primary colors. The color compositions of the points are evaluated to identify color compositions characteristic of skin tones, and a color space is created based on these color compositions. Scanned points whose color compositions lie in the color space undergo an examination to ascertain whether or not they actually represent skin. The examination is concerned primarily with the positions of such scanned points within the exposure and secondarily with density differences between the points and specified zones of the exposure, density differences between adjacent points, and the nature of any groups formed by the points, only those scanned points which actually represent skin are considered when calculating the amount of copy light for the exposure in each primary color.
