发明名称 Photographic printing method
摘要 A photographic printing method in which a plurality of image frames photographed on a negative film by a camera, which photometrically measures different areas on an object by a plurality of photometric elements and which determines an exposure, is printed onto photographic paper. Printing processing is effected at an average exposure of the plurality of image frames. Namely, all of the image frames of the negative film are photometrically measured. Average densities of each of R, G, and B of an entire image surface are calculated. An average value of the average densities of all of the image frames of the negative film is calculated. An amount of printing exposure is determined using this average value. Printing processing of all of the image frames is effected at this amount of printing exposure. Accordingly, a large proportion of prints having appropriate densities can be obtained.
