Could I re-add AgNO3 and KBr after the sensitasation

[narigas2006]

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!

Interesting proposal. Apply gelatine, afterwards soak
in AgNO3 then in KBr. Any ready to soak papers
available? Dan

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.

So it's OK. 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. Dan

Dan, I guess I don't understand this comment.

Sorry.
