Recipe:
In 300ml water at 20 degrees C dissolve

0.4g sodium sulphite (optional)
shake and leave to settle. Then dissolve in this
5.5g instant coffee granules
0.4g ascorbic acid powder
richard314159 processed a roll of ATP in the 300ml version of this formula for 20 minutes. Though he did mention that 18 minutes may have been a better time.
I need to look at the records for last roll of CMS that I shot to see what ISO i chose to use. I seem to remember 12, but i will certainly check. I don't want to think about processing time until I have the exposure details worked out.
The issue that I am having about this is I am slightly anxious about blowing a roll of rare film for an experiment. Considering this I am going to be very careful about subject, shot setup, exposure, and processing.
This came from my last shoot with the Bronica and CMS 20:
I will add more later.
