ABSTRACT:
A photographic printing apparatus comprises a system for discriminating exposure information on a first print and memorizing exposure conditions of the first print corresponding to the exposure information, and a control keyboard for inputting an exposure correction amount of a second print with respect to the first print. Exposure conditions of the second print are determined by combining the exposure conditions of the first print with the exposure correction amount of the second print with respect to the first print. When the second print is produced by a second apparatus different from a first apparatus used for producing the first print, a system for inputting and memorizing a difference in setting conditions between the first and second apparatuses is also provided to determine the exposure conditions of the second print on the basis of the exposure conditions of the first print, the exposure correction amount, and the difference in setting conditions between the first and second apparatuses.
