ABSTRACT:
A process for forming light-sensitive silver halide crystals by adding silver ion and halide ion in the presence of a protective colloid, which comprises producing seed crystals containing multiple twin crystal grains during a crystal nuclei-forming period, maintaining the pBr of the system at about 4.8 to 2.0 during at least the first third of the subsequent crystal-growing period, and increasing the rates of silver ion and halide ion addition to levels at which the crystal growth rate becomes about 30 to 100% of the critical crystal growth rate throughout said crystal-growing period..
