What happens when pottasium ferricyanide is applied on selective areas
of selenium-toned fibre based prints for the purpose of bleaching in
order to retouch the print.
Generally, we use pottasium ferricyanide on prints that have not been
selenium toned in order to bleach to prepare the print for retouching.
Will selenium-toned prints be affected by pottasium ferricyanide?
The selenium is a mild dilution, 1:30, and the prints are washed
throughly after being toned in preparation for retouching.
