摘要:
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., lacking an incorporated dye-forming coupler). 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.
