ABSTRACT:
A photographic element comprises: a support and, coated on the support, a plurality of hydrophilic colloid layers, including radiation-sensitive silver halide emulsion layers, forming layer units for separately recording blue, green and red exposures, wherein, the red recording layer unit is comprised of at least one green-red sensitive emulsion having a peak dyed absorptance of between about 525 and about 600 nm, an overall half-peak absorptance bandwidth of between about 70 and about 150 nm, and a ratio of the bandwidths at 80% of peak absorptance to 50% of peak absorptance of greater than or equal to about 0.25.
In preferred embodiments of the invention, the photographic element is especially suited for more accurately recording scenes according to the human visual system.
