Abstract
An apparatus that produces digitally generated index prints and normal optical prints as part of the normal printing operation, without requiring the negatives to be cut and handled separately. The foregoing is accomplished by using the exposure determination and subject classification data generated for the normal optical printing operation to rapidly provide the low resolution digital data for creating the individual index print images, during the normal optical printing operation. While the digital images are being created, each digital image is being simultaneously corrected for its own exposure requirement.
