Hello,
I'm fond of looking at pt/pd prints.
I would like to experiment the kallitype process and have decided to purchase a kit. However the chemical included in B&S and Formulary kit are different from each other. I'm banding towards B&S kit as it seems substantially cheaper. Is there any differences in procedure and outcome between the two?
Any difference between ammonium & potassium dichromate?
B&S also sells Platinum Toning kit. Is it possible to achieve warm tone with this toning kit? If not, what chemical & quantity is used to make Palladium Toner affordably?
Off topic:
I have left-over silver nitrate, potassium dichromate, gelatine-salt solution mixed 30 months ago. Do you know if they are still good? If not, I'll dispose them all. I'm hoping they can keep for a long time.
Also, slimy clumps has formed in the left-over Fotospeed AU20 gold toner (and algae-looking black spots sticking on the inside glass of the bottle). Still good?
Many Thanks!
