By the present invention, on the basis of information read from a magnetic recording section of a negative film (Step 200), when it is judged that there are a plurality of negative images to be exposed by the same exposure amount (the judgment in Step 212 is affirmative), a film type is identified to determine the film base density thereof, and a predetermined reference density value is added to the film base density so as to obtain a density control amount which controls the density of a print image (Steps 216 through 220). Thereafter, a color balance mean value of a large number of negative images of the same type is detected and a weighted mean value of a color balance mean value among a plurality of negative images to be exposed and the detected color balance value to obtain a color control amount (Step 222). Then, a common exposure amount is computed from the thus obtained density control amount and the color control amount (Step 224) for exposing the negative images to be exposed by the same exposure amount onto a printing paper by the common exposure amount (Step 278).
