Abstract
A photographic printer includes a system for indicating the direction of movement of the dichroic filters required to re-establish color balance whenever a setup is changed. Signals are stored for each of the plurality of setups which are determinative of the desired filter position for achieving color balance with that setup. When one of the setups is selected, a parameter is sensed which is related to the filter position. The signals generated as a function of the sensed parameter are compared to the stored signals, and an indication of the direction of movement, if any, necessary to move the filters to the desired filter positions for that selected setup is provided.
