Visit my new blog

I´ve decided to split my blog in two. I will continue to post DIY projects and musings here, but (serious) pictures, taken on film of course, will be posted in my new blog "Silver Halides"

I now consider Caffenol to be a developer like any else. As such the new blog will focus more on the pictures, rather than the process.

Some catching up to do

Summer has been about all things not Caffenol, or anything DIY at all. Not had the time nor energy to do much testing. Though a few films have been given the once over.

Those that met with success are:

In 135:
Efke KB100, EI200 in Caffenol-C-M (RS), 14 min @ 20C

Leica M4-2, Voigtländer Ultron 28 f1.9, Efke KB100, Caffenol-C-M (RS)
Leica M4-2, Voigtländer Ultron 28 f1.9, Efke KB100, Caffenol-C-M (RS)

ERA100 @ EI100, Caffenol-C-M,13:30min @ 20C


Royal 35-M, ERA 100, Caffenol-C-M
Royal 35-M, ERA 100, Caffenol-C-M


Agfa APX 400, Caffenol-C-H, 13min @ 20C


Leica M4-2, VC Ultron 28mm/f1.9. APX 400, Caffenol-C-H

In 120:

Fuji Neopan 400 @ EI400, Caffenol-C-L semistand, 60min @ 20C. Forgot to add bromide, and yet the negatives came out without streaks and the base fog was well under control. Strange.

Kalloflex K2, Neopan 400, Caffenol-C-L
Kalloflex K2, Neopan 400, Caffenol-C-L

Ilford Delta 400 @ EI800, Caffenol-C-L, 5min presoak, 60min semistand @ 20C

Kalloflex K2, Delta 400, Caffenol-C-L

Lately had a couple of mishaps with Caffenol-C-L. I think I know why. Storing ready mixed solutions for a long time may work with the more concentrated versions, but not for C-L. There you need freshly made solutions, the tolerances are much lower, and any oxidisation or depletion of the substances will have a big effect on the result. C-M/H versions are much more robust to variations in pH.
