Potassium ferricyanide reacts with ferrous iron in acidic solution to produce the insoluble blue pigment, commonly referred to as Turnbull's blue or Prussian blue.
16.
The print is washed to remove excess potassium ferricyanide, and then immersed into a bath of toner, which converts the silver halides to silver sulfide.
17.
The image is then developed using a solution of potassium ferricyanide forming insoluble ferroferricyanide ( Turnbell's blue identical to Prussian blue ) with the divalent iron.
