Bill Williams C-41 developer

Original recipe may be found here.

A 2-solution C-41 developer, based on the original Bill Williams recipe:

Stock solution A, for 500 ml

25g Sodium Sulfite
20g CD4 *

Stock solution B, for 500 ml
12,5g Potassium Bromide
0,1g Potassium Iodide
200g Potassium Carbonate

* The resulting amount in the work solution is slightly higher than Bill Williams recipe, 0,4g against 0,35g.


Put 10ml of each solutions A and B in 500ml hot water from tap (+/- 50ºC), mix and let it cool to 45ºC (112ºF). Pour the solution into the tank, where the film was previously loaded. Gently and constant agitation during 8 minutes. Then rinse, followed by bleach, rinse, fix and wash, as usual.
