[alt-photo] Re: ANY HOPE? TEST FOR RESIDUAL FO & PT/PD

[Philippe Ayral]

Hello Bob,

I don't know any and never read anything about that in all books about
Pd/Pt I already read.
The only control I know is visual. I look from the back of the print
in front of a very strong white light.
If you can see some yellow tint in the coated part of the paper,
clearing is not complete.
Some of my Pd/Pt prints are more than 20 years old and no change till now.
My two cents.
