Resurecting a 'very' old thread I am intrigued by PE's comment that something important is missing from Dignan's formula. Is it Hydroxylamine Sulphate?

What function does this have in C-41 developer and if one should be so bold as to add it to the Dignan formula, would it go into the 1st or 2nd bath or maybe both?

I am not in the professional business and therefore can accept 'acceptible' results and the idea of a home brew appeals greatly. Amazing what color correction in PS can do to slightly 'off' CN negatives! :-) From the local lab, that is. Haven't done any myself, yet.

Could Ron explain further?

It lacks one ingredient I can see, right off the bat, and has an ingredient that can harm proper imaging.

I doubt if anyone should use this for valuable pictures.
