Questions about stabilizers
"Overripening leads to fog and loss of speed and contrast. You must stop this ongoing process by using proper stabilizer.
I bet commercial liquid emulsions are all washed, and probably all bromide based."
I was looking at the MSDS of Liquid Light and noticed that besides the bromide and chloride, there was trace amounts of Cadmium salts.
Are the Cadmium salts used for contrast increase, reduction of fog, and would the Cadmum salts act as a stabilizer?
Just one loud remark: I AM NOT ADVOCATING USING CADMIUM SALTS IN SMALL LAB EMULSION PRODUCTION. They are very toxic and bad for the envirnment.
Enlarging Speed AgBr Emulsion
This is the first post of a picture made using my bromide enlarging speed emulsion.
The emulsion keeps for about 6 months in the refrigerator (with no addenda but Thymol) before sulfur sensitization and the paper itself keeps for about 9 months with little change.
It is very similar to the one posted above in the OP. It was washed. I have gotten similar results from the same emulsion unwashed, but it requires different addenda and a longer sulfur finish.
This is a portion of a portrait taken by a friend and given to me. The exposure was 12" at f11/f16 and the developer was Dektol 1:1 for 1 minute. The print was stopped, fixed and washed.
