Carl,
Thanks for your reply. When Witho was here he showed me some of his
split-toned work but I was not sure exactly how he achieved the
color. When terms like cesium and lithium are used I no longer
understand if this is in the pt/pd, or represents some other variant.
What I did gather from Witho was that the use of these other metals
requires an extremely delicate balance in the mixture.
Is there a good write-up anywhere about these alternate possibilites
with pt/pd?
Sandy
