I have a book that is only about photographic toners. I think that’s where I read that many vintage “platinum” prints are actually platinum toned Kallitypes. Still platinum on the paper in the end.

Could you share the book details?

Sorry for the late reply. Holy cow this thing got expensive! https://www.amazon.com/Photographers-Toning-Book-Definitive-...

It is the most comprehensive guide to toners I have ever seen. Glad I kept a copy of it!
