From 1999 to 2009 I taught the technological evolution of photography to an international group of photograph conservators in the Advanced Residency Program in Photograph Conservation here at George Eastman House International Museum of Photography and Film in Rochester, NY.
While that program is now over, I still work here at Eastman House as the photographic process historian. For the first time I am now at liberty to teach my curriculum to the general public. This includes everything from pre-photographic drawing techniques using camera lucida, tent cameras and physionotrace to the earliest processes of Niepce, Daguerre, Bayard and Talbot and all the way to making gelatin emulsions. And from time to time we have guest instructors.
And yes, I teach collodion. In fact, the very first group workshops in the revival of collodion process were conducted by France [my wife] and me here at the museum in 1995. This year we taught the first public workshop in making collodion chloride emulsion printing-out paper and dry plate collodion negatives. This fall I will be teaching two collodion workshops; a beginning ambrotype workshop and a collodion negative workshop featuring both wet and dry collodion negatives, retouching and salt printing.
Our regularly scheduled workshops usually include the history, theory and hands-on instruction of a specific process, but also viewing rare examples of the featured process from the collections of the museum.
