Been there, done that and reported the results in other APUG threads. To summarize:Originally Posted by donbga
My side-by-side print/developer test results comparing Ansco 130/Azo with Michael Smith Amidol/Azo resulted in a small but noticeable tonality advantage for Amidol/Azo.
I am planning some additional tests using Ansel Adams version of Ansco 130 in a split development scheme (as a soft working warm tone developer). I plan to soak the print in "straight" Ansco 130 for a short time, then transfer the print to the AA version and complete development. Water bath development is an additional contrast control treatment that is appropriate for Ansco 130 development.
Since I use both Amidol and Ansco 130 as one-shots, tray life is not an issue with me. I have found that 1 liter of either working developer will process at least 20 8x10 prints without any noticeable change in performance.
"AFAIK, Photographers Formulary are the only sellars of small quantities of Glycin. "
There are other sellers of glycin in small quantities, Bryant Lab is one. However, it appears that PF currently has the lowest price.
