Re: Some Kallitype observations
I am so glad you posted this and thanks for testing it. For the record y'all, the lower dilution in my Alt Proc Cond book for pot ox and kalli (3%) is not a typo but is an actual formula I came across in a few places. Rajul was kind enough to test it against the normal dilution of pot ox and discovered this, below. Any kallitypists out there, have you used this lower dilution, also? Those of you having problems with kalli staining or some other such thing, have you used the lower dilution or were you even using pot ox? Don Bryant, you do kallis, correct? I am just intrigued by why the dilution of the developer is so drastic and yet works better. Makes me wonder about dilution of our developers with pt/pd and if there is an applicable reason to use diluted developers. Probably not. I had one of my students (Camden, was that you?) try the old 7up or gatorade trick to develop his palladium print and it was a BUST so don't believe it. Maybe he didn't use the right flavor, heheheheh
Undaunted by the variables to choose from, when I saw potassium oxalate (KOX) listed among the slew of developers in Chris's chapter on Kallis in Alt Procs Condensed book, I tried it ( I happen to be overstocked). At 20% concentration, the print developed to a heavy, poorly differentiated detail. Diluted to 5% (I have not gone below this), tonal separations were clear and rendered in great detail. These compare well with prints developed side by side with Hall's developer and with 20% sodium citrate. At 5%, the toxicity of KOX may not be much of an issue (Spinach is loaded with oxalate!). Also, it permits one-shot use to yield cleaner prints, something I found with Pt/Pds.
