I will be giving another workshop on emulsion making and coating at the Photographers Formulary in Montana June 3-8, 2007.
This workshop will include instructions on the making and coating of 3 grades of an Azo type paper (see review here by Alex Hawley).
I will also show you how to make and coat a Brovira/Kodabromide type emulsion, and a slow orthochromatic film emulsion with a camera speed of about ISO 40. (see samples posted here from previous workshops).
You will learn how to add stabilzers, metal dopants and coating doctors to your emulsion to control contrast, keeping and reciprocity failure. You will learn chemical and spectral sensitization and how to control the coating properties of gelatin emulsions on plain paper, baryta and film.
Time permitting, we will also coat some glass plates by the traditional method and also by using a newly designed glass plate coater which uses the method developed by George Eastman for production coating of glass plates in the early part of the last century.
Students are out there now using what they learned to turn out some very good work and one is posting the information on her blog (www.dwrphotos.com).
This is your chance to learn emulsion making and coating first hand from someone who has done it at all Eastman Kodak, or as we called it, the "Big Yellow Jello".
See you there.
