Re: RE: Satista question
Loris,
My favorite paper for this process is COT 320. I use only one pass development. Place enough solution at the edge of the print to cover the whole print in one pass (look at my write up on alternative photography web site http://www.alternativephotography.com/process_satista.html ). The process is messy because silver nitrate will stain everything it comes in contact with. Tray development is another option that you might consider.
In terms of sensitizer concentration, at 40% FOA the sensitizer will frequently crystallize, at 20% it is always smooth. This tendency to crystallize might be paper dependent.
