bw400cn

4strinbass · Apr 21, 2011

I was wondering how everyone develops bw400cn in caffenol? here's what i've been trying to use:

20 oz. Water.
10 teaspoons of instant coffee. (not decaf)
7 teaspoons of washing soda
1 teaspoon of vitamin c

Developer 20min , agitate slowly for one minute, every three minutes.

Wash

Fixer for 5 minutes

Final wash.

I use Ilford Rapid Fixer to try and fix the images. The negatives are always an EXTREMELY light image and the film isn't translucent in the end. I can just barely tell where the exposures were made. The instant I use is folgers.

I don't want to give up on bw400cn too easily.

I have just recently. Though I suspect it is of little value nowadays, since its been discontinued. Both the BW400CN and the previous Portra BW400 versions.

Used the metric recipe from Caffenol.blogspot.com, C-C-H with 1g/l Kbr (may not need the latter though I have not tried it without). 14min 30s at 68F/20C

Works out quite well in fact:
