Hold on. Color film?

Well, you can develop every kind of film in Caffenol (a B&W process, that is) as long as it contains silver. So why not push that to the extreme and use an expired ISO 1600 Film and develop it in Caffenol.

Salt & Pepper

Voigtlaender Vitoret DR f2.8 1/30s.

Fujicolor 1600, expired 2004
Developped in caffenol (No-C) for 30 minutes.

The negative comes out very dense, but as I primarily scan the negatives, this is not a problem.

Scanned using a Slide Duplicator on a Pentax K10D.
