Sounds logical. Changing the sequence will change the look, it's more about being consistent.

Ian : this sounds pretty logical, what do you think. If I bleach and refix after selenium, then move to my sepia tone and gold for the look, ??
Bob... I know you use Kodak Sepia II kits for split tonig. I'd use the part A bleach from one of those packs. I find the stock pot ferri bleach solution to be VERY strong acting. For split toning my prints I dilute it 1:6 or more to get better control over this step and usually for no longer than 30 or 40 seconds. For what you are doing, stock solution might be the ticket to brighten those dull highlights, and crispen them up nicely. I assume you are leaving out the sulphide step and going straight to selenium. That said, the bleach alone at that strenght will tend warm things a little anyway.
Hi Bob,
I often do this selenium/bleach/sepia. You don't need to fix because you go to sepia.
If you just do selenium and bleach, then you fix and wash.

Great stuff Bob
... Perhaps a simpler explanation is that Ferricyanide on it's own attacks the smaller grains first, that's why it's used with or without bromide for split toning, but with Thiosulphate added Farmers Reducers attacks the larger "black" grains as well at the same time. ...
There's too many variables Bob. However a 100g/litre of each diluted 1+10 works very fast, that's 10g/litre, your talking a touch under 3g/litre, I'd start by diluting that a further 1+9 (1:10) so you have about 3g/litre Ferricyanide & KBr
One nice point about using this bleach is if it goes too far, you just wash and re-develop, the room light is usually sufficient to re-expose the bleached emulsion.

is there no need to refixing using Farmers Reducer? just proceed with normal washing?
It's advisable to re-fix in fresh fixer after Farmers Reducer as fixing may not have been complete.
can I mix parts of the package, or is it nescessary to mix it all at once?
Does anyone here bleach as a standard part of their print process? ...

There's a great Seattle area photographer who's known for "printing down, and bleaching up."

Will Potassium Ferricyanide keep as a stock solution, in a brown glass bottle?
I make a 10% Potassium Bromide solution. Could I do the same with the ferri?
Thanks!

From what I can tell, it lasts for a long time (years). I usually make a 1% solution with distilled water, but anyway, dry potassium ferricyanide keeps for decades.
why distilled water?
Storing such a weak solution distilled is better, however it's more normal to store as a 10% solution, and it all depends on how pure your tap water is if you don't use deionised or distilled water.
