Following the thread on Ilford Multigrade and selenium toning, this is one of a series of photos demonstrating mild bleaching, and bleach redevelopment prior to toning.
As for the straight print, but then bleaching in dilute ferri bleach (1+39), with added NaCl. Bleached for 60 seconds to demonstrate how quickly the highlights start disappearing. Then selenium toned, as for the straight toned print.
