    摘要: The present invention is directed to a process of precipitating for use in photography a thin, tabular grain silver bromide or bromoiodide emulsion employing a gelatino-peptizer comprised of less than 30 micromoles of methionine per gram and to an emulsion produced by this process. A variety of advantages can be realized, including a wider range of permissible bromide ion concentrations during precipitation, thinner and/or larger diameter tabular grains, a reduced rod population, and novel tabular grain forms.
