Just an add on incentive....
Today I shot my first ISO 200 paper negative with ortho sensitivity. I'm still working on extensions to add to the class to make it an outstanding learning experience for all who attend.
BTW, the same thing on film support was about ISO 25 - 50. It still has faults such as high fog and low contrast, but I am moving forward and will pass this and more on to the attendees in complete detail.
For those interested, this is an SRAD (Single Run Ammonia Digest) AgBrI, with optimal sulfur sensitization (no gold yet) and with a spectral sensitizing dye. The emulsion was precipitated in Phthalated Gelatin and ISO washed with an acid base cycle. It takes about 3 days to make properly and has 2 digest steps, each about 1 - 2 hours long.
All chemicals to make this and the other emulsions will be available to students at the workshop and I have hopes that the Formulary will be able to stock and sell the dyes, dopants and antifoggants. This includes rhodium and iridium salts among a host of others. Twenty coating blades are on order (10 each in 2 sizes) to be available at the workshop. This is rev 3 of the blades. The redesign was done to facilitate coating on film and baryta support among other revisions. I also have the first sample of a film coating blade which will be available at the workshop. It may not be ready in quantity by then.
I would also like to add that I zipped out to the Formulary in July of 2005 and made the AgCl emulsion for Bud and Bill Troop. They walked with me through the entire process from making to coating to exposing and processing. It worked perfectly. I gave Bud the prints.
I look forward to meeting you all there.
Best wishes and thanks to you all for the many messages and all of the support.
