My first thought was...Photo Engineer, Ron Mowrey!

8 people just got a crash course in emulsion making 2 weeks ago at the George Eastman House (GEH) and each one of us could probably comfortably do it by ourselves now. I'll admit, I didn't take this class because I immediately wanted to go home and make some prints, but rather to learn it while someone with the expetise is willing to share it!

Ron is one of very few emulsion evangelists.

Though, I know there are people Australia that are working on some pretty exciting things when it comes to emulsions.
