Abstract
A system and method for electronically developing an image recorded on film by applying a developer to and then scanning the film during the development at a number of spaced timed intervals. Images are captured during each of the spaced scans and are stored as digital representations of that scan. The stored digital representations are combined on a pixel-by-pixel basis to produce an output image that differs from any one of the stored representations. This combination of digital images allows for optimal image development without actually forming or storing the image on the film itself.
