ABSTRACT:
A photographic element capable of forming a reversal image is disclosed having an emulsion layer containing a blend of spectrally sensitized tabular iodohalide grains and a second, slower fine grain population of a higher overall solubility silver salt content for increasing speed and contrast. A second dye is adsorbed to the surface of the second grain population to provide a further increase in threshold speed.
