ABSTRACT:
A process and apparatus for mass-producing a silver halide emulsion for photographic light-sensitive materials which includes carrying out the nucleation of the silver halide grains in a reaction apparatus having a middle capacity and carrying out physical ripening and/or the crystal growth in a reaction apparatus having a larger capacity than the middle capacity reaction apparatus. Another reaction apparatus having a larger capacity than the middle capacity reaction apparatus can be used to store nuclei formed in the middle capacity reaction apparatus before transfer of the nuclei to the other reaction apparatus having a large capacity in which physical ripening and/or the crystal growth are carried out.
