1. A photographic printing method for printing a film image of frames of a film onto photographic paper by correcting a print exposure amount determined on the basis of an image density of the film image, comprising the steps of:

  • estimating color quantity of a subject illuminant for each of the frames based on information recorded at the time of photographing;

    changing, in correspondence with the color quantity estimated, a degree of color correction of the image density for each of the frames in which an improper color balance occurs in color reproduction with a change in the color quantity of the subject illuminant; and

    determining the print exposure amount to control the color of a print in correspondence with both a density difference between the image density of the film image to be printed and an average image density and the degree of color correction.
