ABSTRACT:
A process for preparing a thin tabular grain silver halide emulsion comprised of silver halide grains which have a halide content of at least 50 mole percent bromide, wherein tabular grains of less than 0.15 micrometers in thickness and having an aspect ratio of greater than 8 account for greater than 50 percent of the total grain projected area, comprises the steps of nucleating the silver halide grains with a gelatino-peptizer or with the use of certain synthetic polymers that serve as effective nucleation peptizers and then growing the silver halide grains with the use of either a gelatino-peptizer or certain synthetic polymers that serve as effective growth peptizers.
