Edwal TST

On a search I've not found a single solitary
comment regarding Edwal's TST print developer.
Can it be that no Apug responder has any experience
with Edwal TST? Dan

TST was my favorite developer for Agfa Brovira paper which I used it at its most concentrated dilution (1:15?). It gave me very beautiful neutral toned prints, but of course much of that was the paper itself. Unfortunately, I haven't used it in about 25 years and don't know how it will work with current papers, but I think it's worth a try. I have fond memories of it. If you buy it in a large size I would split it into smaller bottles as it tends to go bad when exposed to air. Good luck.

I had no idea it had been on the market for so many
years. We are talking about the same developer? A
two part, A and B, Edwal contrast control print
developer?

A current thread, VC vs N+ and N-, speaks only of
those two options for controlling a print's resultant
contrast. Ansel Adams used Beer's and his own
version of Ansco 130 developers for varying
contrast. So those two plus the off the
shelf Edwal TST.

My interest in whole print and local contrast control
methods centers on the use of Graded paper. Dan

Dan,

Sorry for the delay. Yes, TST has been around a long time. I think a developer like TST or any other where you can adjust the contrast is a very viable way to print and gives a bit more control with graded papers. Have you tried a 2 bath system with 1 tray of high contrast developer and 1 tray of a softer one? The print is developed partially in the higher contrast developer and completed in the softer one. By varying the time in each solution, the contrast can be moved up and down. I think Beers would be ideal for this, although many people just use something like Dektol and Selectol.

If you try this, please let us know how it works for you. Good luck.
