View Full Version : hardeners for fixer and bleach for sepia
hello all,
i have some powdered kodak sepia toner but i do not have the bleach. i like mixing my own chemicals. what do i need?
i also have been using sodium thiosulfate for my fixer. what do i want top use if i want to harden the negs?
thanks
eddie
Modern films are pre hardened so it's not normal now to add a hardener.
The Bleach can be Potassium Ferricyanide and Potassium Bromide for the toner, or Sodium Chloride instead of the Bromide for even warmer tones.

i forgot to say. i use foma films. are they hardened?

Foma films are fine, they don't need a hardener.
The Bleach should typically be:
Ilford IT-1 Bleach
100gms Potassium Ferricyanide
100gms Potassium Bromide
Water to 1 litre
Dilute 1+9 for use.
The stock solution has a long shelf life.
