Do you have any examples to show? I'm interested in seeing what the grain is like. One would think that a slower film would have better grain... but having used copy film I know better.
I have posted quite a few here, and at the risk of using up Sean's storage space, I guess I can do it again. Left is an ortho sensitive version of the emulsion in the OP, using PA gelatin and ISO washing. The sensitizer was Erythrosine. The right image is a Scanning Electron Micrograph of the emulsion. The results in this case are independant of whether Dye is added or regular or ISO washing is done. I have checked them out with SEMs also.
