I also posted this to r.p.d., but since there seems to be a different group here I thought I'd try it here too.
I was thinking of trying some glycin paper developing formulas, and a few questions came to mind. Has anyone used any of the print formulas at http://www.jackspcs.com/chemdesc.htm#GLYCIN (other than Ansco 130, which will be my first try), or have any other good glycin formulas?
I asked a few days ago about brown, not green, warm tones, but didnt see any replies. I've seen glycin described several places as producing a warm brown or (in the case of D-155) even reddish brown tone. Maybe this is what I'm looking for?
What other qualities do prints developed with glycin have?
I've read that the powder doesnt keep well, but that glycin developer solutions keep very well. Since its also somewhat more toxic tha other reducers, I'd like to minimize my exposure to it. Could a person make a concentrated long-lasting alkaline X% solution to dilute as needed, or do the stock solutions last long enough to make this unnecessary? (Formulary claims some of their glycin-based stock solutions last 1 year)
