    Thanks PE for explaining this technically!

    PE is right, figure out what you want your work to look like, then formulate your chems. For me, I wanted the stain in my work and that is why I omitted the clear (ie Acetic Acid and Sodium Sulfite) and why my photo below looks as such (which I love):

    I want it as close to E6 as possible, but with its own twist in color and expression. In my process the bleach is the key problem. Kodak C41 bleach is, as PE says, too weak. I havent tried the RA4-bleach (not blix) and im now testing out what will be the best dillution of my SPUR version of Farmers reducer http://www.macodirect.de/spur-liquid...ml-p-2093.html

    You can use Farmer's reducer, but you must use a clearing bath between the color developer and bleach. I have explained that elsewhere here.

    Can i use Sodium Sulfite (anhydrous) to make this clearing bath? If so, how many grams pr. litre of water?

    Use about 5 - 20 g/l in a common 1% - 2% stop bath of acetic acid. This should be an effective clearing bath for all strong (Ferri, Persulfate or Quinone) bleaches. Do not use Dichromate - Sulfuric Acid bleach at all for this type of process.

    Make sure you wash well after the bleach and after the clearing bath.

    Will try this out now. I mixed 50ml + 450 ml of the part A of the Farmers Reducer to make the Bleach. By the way. Isnt Sodium Sulfite , the one i posted picture of, in real terms a Hypo Clearing Agent? Just liky Hypo Clearing from Kodak? I have uploaded a picture of the bottle i made bleach of.I used only the A part in 1+18 dillution.

    Look at the ingredients in part B! It contains hypo! If you wish to remove the silver completely and have no further action then use it but if you need to retain the silver do not use this.

    The ferri bleach I referred to is Potassium Ferricyanide + Potassium or Sodium Bromide. This bleaches. Then you fix in a separate step.
