Process of preparing high bromide (100) tabular grain emulsions |
摘要 |
A process of preparing a high bromide {100} tabular grain emulsion is disclosed wherein mean ECD of the tabular grains obtained at the conclusion of ripening is controlled by the use of chloride ion. Specifically, both the concentration of chloride ion introduced before grain nucleation and the proportion of chloride ion and bromide ion present during nucleation are shown to allow control of final mean grain ECD in the fully ripened emulsion.
