In this video I show I do to a split-toned image Sepia-Selenium in the darkroom.
Paper: Ilford MG FB classic Glossy
All process at about 20 deg C
1. Bleach
30 sec in 15 g/L potassium ferricyanide + 8 g/L potassium bromide
2. Sepia toner
1 min in 2 g/L thiourea + 8 g/L potassium hydroxide
3. Selenium toner
2-3 mins in Ilford Selenium toner diluted 1/10
Note: the actual formulas of the silver halides salts formed during the sepia and selenium toning are AgS2 (silver sulphide) and AgSe2 (silver selenide) respectively. I used simplified--but incorrect--formulas in the video (AgS and AgSe).
