RE: RE: Satista question
I've made a print on COT320. It's better but I still have uneven development problem (especially at the edge where the excess AgNO3 waits before blotting). I get staining too -> the developer carries silver sludge to the end of the image and stains the edges black. Unfortunately I decided the process is not for me -> I can't get a clean image by my standards -> back to sweet home POP Pd :) BTW, as a final note: exposures are quite fast (1:15 with my exposure unit), shadow + middletone contrast is quite high, highlight contrast is quite low... Regards and thank all for their help, Loris. -----Original Message----- From: Marek Matusz [mailto:marekmatusz@hotmail.com] Sent: Monday, March 19, 2007 8:18 PM To: alt-photo-process-l@usask.ca Subject: 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.
