    Formulary Potassium Ferricyanide (Bleach) Powder 1 Lb. (this is a rehalogenating, right?)

    Unless it contains Potassium or Sodium Bromide, or Chlorise on ut's own Ferricyanide is not a rehalogenating bleach.

    Some people use a plain Ferricyanide bleach (no bromide) others add bromide, and if you add Thiosulphate to plain thiosulphate you have Farmers reducer.


    There's no set rules, papers vary substantially as Bill says soit's trials and experiments first to get the effects you desire.

    Fiber paper is fixed in TF-4 fixer. Transferred to a mixed solution of Kodak hypo clearing agent and selenium tone. Wash for one hour. This method has served me well for 20+ years. When TF-4 was introduced.

    So does it matter how the print was originally fixed if it has been archival washed and dried? Do I only need to use the TF-4/5 when using the selenium ... not when developing?
