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.
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.
