Hi all,
Richard, Thank you for a very lucid explanation of how paper dries?
I've used screens, face up. From my neighbour who is closing his
darkroom because he is returning to Switzerland, I recently received 6
rolls of Kodak Blotting Paper, 11.5" x6'.
I'll try the blotting paper route, but I would like to know if there are
pros and cons to each method. And why?
Thanks!
Cheers,
Bogdan
