: Can someone more knowledgeable than me please confirm that in : traditional colour processing - negative C41 and print RA4 processes, : that the end result, negative or film, will not contain any *silver* : grains at all? they do not .. : My understanding is that the bleach fix step if properly applied : converts all silver metal to silver cations (by the ferric containing : EDTA, and the ammonium thiosulfate then removes all the silver halide, : i.e. silver cations? that's th way it's supposed to work! :) : : A colleague on another forum has suggested that all colour prints : produced by the wet colour print process will show silver grains... : He quoted the Kodak reference: : <http://www.kodak.com/global/en/professional/support/techPubs/e58/e58.jhtml : <http://www.kodak.com/global/en/professional/support/techPubs/e58/e58.jhtml >> : as confirming his point, but it doesn't tie in with the chemistry that I : understand. I think they are using the silver grain produced in : traditional B&W prints as the standard for comparison. : (I'm probably being very pedantic here!) I read this in the top page ref: "DEFINITIONS Grain A particle of metallic silver or a cloud of dye in a photographic emulsion. Exposed silver halide crystals in raw emulsion that become grains in the photographic process. " 'cloud of dye' is what's left in c41/e6/ra4 after processing
