ABSTRACT:
A photographic element is disclosed comprised of a sequence of superimposed blue, green and red recording silver halide emulsion layer units at least two of which produce images of the same hue upon processing. The photographic element is additionally comprised of, interposed between the two emulsion layer units, an interlayer unit for transmitting to the emulsion layer unit of the two units which is nearer the support, electromagnetic radiation that this emulsion layer unit is intended to record and capable, after processing, of reflecting electromagnetic radiation within at least one wavelength region. The imagewise exposed photographic element can be photographically processed to produce a silver image in each of the emulsion layer units, and can be reflection scanned utilizing reflection from the interlayer unit to provide a first record of the image information in one of the two emulsion layer units and can be reflection or transmission scanned to provide second and third records of the image information in the other two emulsion layer units. The first, second and third records can be compared to obtain separate blue, green and red exposure records.
