ABSTRACT:
A system for electronically developing an image captured on a film with two or more image capture layers. A developing solution is applied to the film and the film is illuminated by two lights on opposing surfaces. A scanner captures the light reflected from the film by each light source. The two digital images are combined on a pixel-by-pixel basis to form a final image. An alternate embodiment includes a third scanner to capture light transmitted through the film in order to form a third digital scan image which is then combined on a pixel-by-pixel basis with the other two images to form the final image. The invention provides a method for creating an image digitally without first creating an image in the film itself.
