Photographic printer with preset correction buttons

Claim 1

For use in a photographic printing system, the improvement comprising: a plurality of incremental correction keys each for requesting, when actuated, an incremental color or density correction; alterable storage means for storing a plurality of combinations of incremental corrections, each combination comprising more than one incremental color or density correction required to correct a recognizable cause of off-balance photographic prints; a plurality of preset correction keys each for requesting, when actuated, one of the plurality of combinations of incremental corrections stored by the alterable storage means; operator control switch means for selecting a first or a second operating mode; and digital processor means for receiving signals from the actuated incremental correction keys, the actuated preset correction keys, and the operator control switch means, the digital processor means storing in the alterable storage means the combination of incremental corrections requested by the actuated incremental correction keys in a memory location associated with the actuated preset correction key when the operator control switch means selects the first operating mode, and totalling the corrections requested by the actuated incremental correction keys and actuated preset correction keys and providing exposure correction signals as a function of the totals of corrections when the operator control switch means selects the second operating mode.
