ABSTRACT:
A method of making a high-quality print avoids carrying out photometry twice on images on a film. In a first transporting process for transporting the film in a first direction, photometry is carried out on all of the images on the film that are to be copied by dividing the images into a number of pixels, logarithmically transforming thus obtained photometric values into photometric data sets, and storing all thus transformed photometric data sets in correspondence with individual images on the film. At least some of the photometric data sets are used to determine a condition of selection for selecting photometric data of pixels. The photometric data thus selected is used in determining the exposure amount of the images, and photographic prints are made during a second transporting process using the determined exposure amounts.
