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.

Abstract:
A method is disclosed of obtaining from an imagewise exposed photographic element separate records of the imagewise exposure to each of the blue, green and red portions of the spectrum comprising photographically processing an imagewise exposed photographic element comprised of a sequence of superimposed blue, green and red recording silver halide emulsion layer units that produce images of the same hue upon processing. A first interlayer overlies the emulsion layer unit nearest the support for transmitting to it imagewise exposing radiation this emulsion layer unit is intended to record and for absorbing after photographic processing scanning radiation within at least one wavelength region. A second interlayer underlies the emulsion layer unit farthest from the support for transmitting to the underlying emulsion layer units exposing radiation they are intended to record and for absorbing after photographic processing scanning radiation within at least one wavelength region. The imagewise exposed photographic element is photographically processed to produce a reflective image in each of the emulsion layer units and is reflection scanned utilizing the absorption of the first and second interlayers to provide the image information in two of the emulsion layer units. The photographic element is scanned through the interlayers and all of the emulsion layer units to provide a spectrally undifferentiated third record of the combined images in all of the emulsion layer units. The first, second and third records are compared to obtain separate blue, green and red exposure records. In the photographic elements of the invention the interlayers remain or become light absorbing after photographic processing.
Abstract:
A method is disclosed of obtaining from an imagewise exposed photographic element separate records of the imagewise exposure to each of the blue, green and red portions of the spectrum comprising photographically processing an imagewise exposed photographic element comprised of a sequence of superimposed blue, green and red recording silver halide emulsion layer units that produce images of the same hue upon processing (e.g., units lacking a dye-forming coupler). A first interlayer unit overlies the emulsion layer unit nearest the support and is capable of transmitting to it imagewise exposing radiation this emulsion layer unit is intended to record. A second interlayer unit underlies the emulsion layer unit farthest from the support and is capable of transmitting to the emulsion layer units lying nearer the support imagewise exposing radiation these emulsion layer units are intended to record. The imagewise exposed photographic element is photographically processed to produce a silver image in each of the emulsion layer units. After photographic processing one of the interlayer units is capable of absorbing electromagnetic radiation within at least one wavelength region and emitting within a longer wavelength region, and the remaining of the first and second interlayer units is capable of reflecting or absorbing electromagnetic radiation within at least one wavelength region. The photographic element is scanned utilizing emission from one of the interlayer units to provide a first record of the image information in one of the first and last emulsion layer units and is scanned utilizing reflection or absorption of the remaining interlayer unit to provide a second record of the image information in one other of the emulsion layer units. Additionally, the photographic element is scanned through the first and second interlayer units and all of the emulsion layer units to provide a spectrally undifferentiated third record of the combined images in all of the emulsion layer units. The first, second and third records are compared to obtain separate blue, green and red exposure records.
