Hi,

About developing kallitypes in silver nitrate, Steven also mentioned
that the problems would be staining everything the developer touches
(including the printer) and controlling the decrease of the silver
nitrate in the solution.
Would the Pt in the developer behave the same way and how to control Pt
concentration?
About toning kallitypes with Pt/Pd, is it more economical than printing
directly by these salts?
How about Rhodio, isn't is very close to Pt/Pd? People use it to finish
jewelry don't they.

Thanks

Joao
