Controlled reduction of silver halide grains formed during precipitation

| Zusammenfassung: | The preparation of a silver halide light-sensitive emulsion is improved by creating reduction reaction conditions during precipitation of the silver halide grains at a time prior to the end of physical ripening so as to form reduction centers. But the creation of the reduction centers is controlled to prevent production of nuclei which result in spontaneous development. |
