Abstract
A photographic image exposing apparatus includes a white light source and a filtering device provided between the white light source and a photographic paper. The filtering device has color filters corresponding to respective light spectrums and is operable to interrupt a light beam traveling from the white light source to the photographic paper to separately allow the corresponding light spectrums to pass therethrough. A light amount adjuster is operable to change respective interrupting times of the color filters with respect to a predetermined exposing range.
