ABSTRACT:
A photographic printer includes incremental correction buttons or keys to permit the operator to request incremental color or overall density corrections. In addition, preset correction keys are provided which allow the operator to request a correction for a recognizable cause of off-balance prints such as incandescent or fluorescent lighting or snow scenes. The preset correction keys represent the desired correction for these recognizable causes which represent a combination of more than one incremental color or density correction.
