A Note on the Structure of Rehalogenated Image
J.R. Fyson, G.I.P. Levenson · The Journal of Photographic Science · 1980
When developed-image silver is bleached in a ferricyanide-bromide solution the silver bromide does not retain the filamentary structure but crystallizes into grains the size of which depends upon the bromide concentration. At high bromide concentration (100 g/l). the reformed grains are as large as those of the original emulsion.
