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,

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
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.
