But glacial acetic acid, 99.7%, is corrosive and can burn skin on contact.

In college, I studied the Dye Transfer photography process. For one part of the process, we used glacial acetic acid, but I don't remember the dilution. IIRC, it was to "eat away" the part of the gelatin emulsion that had not been exposed.

My dad was a PhD chemist. I was asking him about the various chemicals we used. That was one he told me to be very careful with.

Sadly, Kodak discontinued making all the films, papers, and chemistry for Dye Transfer in 1993. Another one lost to the digital age.

For the original image, we shot 4x5 Ektachrome. 4x5 Kodachrome was discontinued before I was born, I think.

Yes I know. I worked for a division of International Paper, their films and dyes division. They put it up for sale and Kodak Polychrome Graphics bought it and closed the site shortly after.
Happened again with the PCB manufacturing division of IBM. I worked for IBM Endicott, the birthplace of IBM. They sold it. The new owners ran it down to a small shadow of it's former self until it went into bancruptcy. The partner owners split up, one of them bought the bancrupt company for pennies on the dollar and it limped along for another 5 years before being sold to TTM and closed. The vast majority of the buildings that housed all the equipment are now vacant. There are several standing on North Street that have been abandoned for so long you can smell the mold and mildew from the sidewalk.

This was one of my processes: Bondfilm

This was the Gold Plate line where I spent most of my time. The minilab is straight ahead, the plater to the right.

Depressing.

Yup.

About 14 years ago, the photo lab I worked at moved to a new location. They decided not to process film anymore because there was so little demand. They couldn't GIVE the film processing equipment away. Hundreds of thousands of dollars worth of equipment went into the dumpster. The same with the enlarger that did 4'x8' murals.

One of the first friends I made at IBM Burlington in '79 moved to Endicott many years ago because they could afford to buy a house in Vestal, not so much here. I guess he retired when they sold it off.

Most of Vestal has higher priced houses for this area.

I used it somewhat frequently. I’m going to have to rethink this years Christmas cards & gifts.
