ABSTRACT:
A method is disclosed of extracting independent spectral image records from an imagewise exposed photographic element that contains superimposed silver halide exposure recording layer units each containing a latent image derived from a selected region of the spectrum. The photographic element contains N+1 superimposed silver halide exposure recording units. Photographic processing is conducted to produce a silver image in N+1 of the exposure recording units and a dye image distinguishable from other dye images in at least N exposure recording layer units. The photographic element is in one instance scanned in a spectral region of silver absorption and minimal image dye absorption to provide a first image density record, and the photographic element is also in N spectral regions wherein maximum density of a different image dye occurs to provide N additional image density records. Information from the separate image density records is converted to N+1 image records each corresponding to a different latent image in the exposed photographic element.
