| View Full Version : Could I re-add AgNO3 and KBr after the sensitasation narigas2006 02-15-2007, 12:10 AM Hi all, If I end up with a weak emulsion and I wanna re-add silver and k salts and go through all the steps, would it be possible? Also, what would be a nice anti-fogging agent? Cheers! dancqu 02-15-2007, 06:47 AM Hi all, If I end up with a weak emulsion and I wanna re-add silver and k salts and go through all the steps, would it be possible? Cheers! Interesting proposal. Apply gelatine, afterwards soak in AgNO3 then in KBr. Any ready to soak papers available? Dan Photo Engineer 02-15-2007, 10:52 AM What are you making? If it is a silver halide emulsion, you cannot add more silver and halide after sulfur sensitization. It covers up the work you just did in sensitization.

No need to incorporate the silver halide into the gelatine at time of coating. Perhaps a method of no use for those who coat at home. The entire paper would be taking up solution. Just a thought.
