I do quite a lot of very dilute bleaching (1:100+) and toning using sepia and selenium. I mostly use Ilford Art 300, MG Fiber WT or MG FB. My typical process goes something like this: Print Develop, Stop, Fix, 10 min inse in archive washer, 10 min Hypo wash, 20 min Rinse in archive washer Dry Then I take to toning and it goes something like this: Soak prints in water Bleach (very dilute e.g. 1:100) Quick rinse in water tray Sepia tone (very dilute e.g. 1:100) Quick rinse in water tray Selenium tone 20 minute wash in archive washer I sometimes use carbon, sienna or blue toning. Does this toning process require any fixing or are my prints sufficiently stable?
