Re: Silver Halide Recipe / Formula please

Adhesion to substrate is main problem during processing. Archival quality is connected mainly with type of developement and namely with final wash. GP-2 followed by fix and properly washed is superior for long term stability, similar as B&W photography. Unfortunately, this chemistry cannot be used ...

They are very easy to make yourself.
As I did, I can report them, but unfortunately only in Russian.
