[Alt-photo] Re: Argyrotype on Fabriano Artistico Extra White Soft Press 300gsm (140lb)

[Marek Matusz]

Loris,
 
I noticed that when I put the files in the same folder for upload. SO I took both prints and examined them side by side. The print on Fabriano SF is indeed somewhat  lighter, perhaps half the step. I think that the contrast is lower then the print of Rising Stonenge. 
 
On a separate note. Does anybody know what is the shelf life of coated argyrotype papers? The chemistry seems to be pretty stable.
 
Marek
