Some years ago a used a similar bleach for color reversal film. It softened
the emulsion so much that it started to slough off the film base. I would not
recommend its use. A potassium dichromate or potassium permanganate bleach
would be preferable.

Alright bleach fans, I am looking for a better understanding of how copper
works in a bleach.
I would like a few different formulas if anyone is willing to share.
Anyone have any tidbits of knowledge they would like to share?
Thank you,
