I've just posted the complete Zimmerman Gum process article from Photo
Miniature October 1910. Go to:
http://www.bostick-sullivan.com and look on the index page in the upper
right corner under processes and you will find the link. They're big and
slow as I scanned them at 300 DPI and posted them whole due to the rather
poor quality of the originals.
It's a rather long and chatty work and is 20 images. Each one two pages
double up but many are facing page images which due to xerography of the
originals done in the early 70's are just shadows.
The topic is interesting in that there may be hints as to how enlarging
speed gum is achieved by the Fresson's. I have a theory!
I just returned last week from France where I visited some carbon printers
and spent part of a day with the Fressons. The visit to Michel Favre and
Pierre Brochet ateliers was enlightening. The Fresson's were kind enough to
give me a tour of the facility and watch prints being exposed (enlarged)
and developed. Nope -- I didn't see the coating machine!
Christian Nze and Jean-Marc Dugas played host and shuffled Bostick and I
around the Isle de France. We had a great time. Pierre Brochet is 83 and is
hunkered down in Photoshop when not making Gravures for the Bibliotheque
Nationale of Charle Negre photos, or the most luscious carbon prints ever
seen. Pierre makes his on carbon tissue on his homemade coating machine. He
also does Dags! Art keeps you young. Michel also has his own roller coating
machine for carbon and even though he is paraplegic from an auto accident
he is an active photographer and carbon printer.
Christian was kind enough to take us to the Societe Franciase Photographie
where we literally drooled over boxes of Puyo's and Demachy's and other gum
printers. Seeing Fresson, Artigue, and Arvel, process gum prints is eye
opening. In comparison to work done in general today this work is truly
humbling!
