ABSTRACT:
A condition-setting method for a photographic printer is disclosed, which is capable of performing the condition-setting work both simply and rapidly. In setting conditions for a digital exposure section, a single condition-setting image data having added thereto a correction value for the condition-setting process that has been performed at a surface exposure section is produced by an image signal processing section and stored in an image memory. A subsidiary control section sets an exposure time for the digital exposure section on the basis of the condition-setting image data stored in the image memory. The conditions need not be set for the digital exposure section using a plurality of Bull's eye negative films having different negative film densities, thereby simplifying the condition-setting job.
