regarding platinum toner for argyrotypes and others
Christopher James' book notes a platinum toner for POP prints using citric acid and platinum solution (10g citric acid, 7-15 drops platinum solution in 1,000ml water). Could this same toner be used for argyrotypes?
I know that Loris has talked about palladium toners et al, but I was wondering if the above formula would work as well...and while I'm here...does anyone have a recipe for a palladium toner that would work for argyrotypes?
Thanks! Have a great Monday wherever you are...
