PURPOSE:To form a color image with a high color purity by image-wisely exposing a color photographic sensitive material through a specified filter on the way to an optical path, and said filter selectively absorbs a light having the wavelength region of a laminated part of photosensitive wavelength regions of a blue sensitive layer and a green sensitive layer of a color photographic sensitive material respectively, and a light having the wavelength region of the laminated part of those of the green sensitive layer and a red sensitive layer of said material respectively. CONSTITUTION:The color photographic sensitive material is image-wisely exposed through the filter capable of absorbing the lights having at least the wave-lengths of 490-510nm and/or 580-600nm respectively as a filter material capable of absorbing the light. The wavelength region of 490-510nm is that of the overlapped part of the blue sensitive layer and the green sensitive layer of an ordinary photosensitive material, and the wavelength region of 580-600nm is that of the overlapped part of the green sensitive layer and the red sensitive layer. The photosensitivity in the unnecessary wavelength region about each layers of the blue, the green and the red sensitive layers is prevented. Thus, as the photosensitive wavelength region can be blocked by said filter, the image with the high color purity is obtd. |
