ABSTRACT:
A photographic printing apparatus includes a reading device for reading image information from a film, and an exposure condition computing device for computing exposure conditions for exposing a photosensitive material based on the image information read by the reading device. The apparatus further includes an image information converter for converting the image information read by the reading device into image information expected to appear on the photosensitive material when the photosensitive material is exposed to the image information on the film under the exposure conditions computed by the exposure condition computing device. The image information converted by the image information converter is displayed on a monitor. The exposure condition computing device receives instructions through a control panel to correct the exposure conditions for the image information displayed on the monitor, or instructions not to correct the exposure conditions. An exposure device exposes the photosensitive material under exposure condition computed by the exposure condition computing device based on correcting instructions inputted through the control panel. The exposure device is operable in parallel with an input from the control panel to the exposure condition computing device, to exposure the photosensitive material to image information for which the exposure conditions have been corrected based on the correcting instructions from the control panel or for which non-correction instructions have been received.
