Precipitation of high chloride content silver halide emulsions

A high chloride {100} tabular grain emulsion is disclosed containing a non-uniform distribution of iodide to increase sensitivity. A high percentage of the {100} tabular grains have one or more crystal lattice dislocations lines at sites of maximum iodide concentration. The dislocation lines are distinctive in that they are oriented parallel to at least one edge of the {100} tabular grains. The mechanism for producing the dislocation lines relies upon a relatively slow rate of addition of iodide ion, improving the reproducibility of emulsion properties in manufacture. Relatively low overall levels of iodide are employed, allowing rapid rates of development.
