what recipe do you use ? one of the ones in the silver gelatin book ?
i have this book as well !
it is great resource for info on coating, processing &c but from
all reports the emulsion recipes are iffy ...
the best place to learn about making emulsions from scratch is the light farm (
http://www.thelightfarm.com )
proven recipes and information from people who use them. ( including mark ostermann at the george eastman house )
years ago i made an emulsion in a house i lived in when i was in college ( the 1980s ) using a recipe from an ancient photographic annual from 1904 ...
it wasn't hard, but didn't come out very good .. so i gravitated to liquid light which i have used on and off for 30 years ...
when i run out of film ( and i am just about there ! ) i will be making chris pattons sea water emulsion, it is simple; and i can't wait !
it is: gelatin, silver nitrate and sea water ( or salt added to water if you have no sea near you ) ... nothing else !
my problem is that i have film that i need to use up, because once i start to make my own emulsion, i don't plan on buying commercial film, paper &c anymore ...
