I purchased Arentz's book on Pt/Pd print and am going to give it a try. Several folks have suggested that I purchase all the chemicals separately instead of as a kit. If I am to do this I need to decide what developer and clearing agent to use. B&S and Photographer's Formulary both include different chemicals in their kits. Thus, my question is what are the pros and cons of each choice.
The B&S kit includes Ammonium Citrate as a developer. Formulary uses Potassium Oxalate. Arentz list them both as developers. Is one preferable to another? Is one considered tried and true? I understand the Potassium Oxalate is never discarded. Is this true for Ammonium Citrate?
What about a clearing agent? B&S includes EDTA in their kit. Formulary uses Citric Acid. My understanding is that citric acid is stronger(more efficient?) than EDTA.
My plan is to start with a tried and true setup as a baseline for experimentation. Crane's Platinotype seems to be the paper that is best suited for this. The coating solutions also seem straightforward. I am going to start with the A+B+C method prescribed in Arentz's book.
Any suggestions would be greatly appreciated.
