[pure-silver] Re: Was Ilford -- Sulfide toners?

Eric Neilsen Photography a écrit :

I was told that myth years ago and never challenged it, but selenium prints
do bleach and tone in a sulfide toner. You can tone in either order but the
colors will be different and the cross toning will be different.

Quite frankly, I tried to bleach a selenium toned print some time ago and I never succeeded. Perhaps I was using the Kodak stuff at the time (I now use a much more powerful soup with 40g of ferricyanide per liter) I don't remember. But I wonder how a silver selenide molecule can revert to silver salt in ferricyanide and then be turned in silver sulfide in sepia bath. It must work only with prints partly toned in weak selenium solutions, where a lot of metallic silver atoms are still available.
