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.

would you please explain us what’s the difference by using or not using the vitamin-C? And 30 minutes is a lot of time, is that because of the color film? I have a lot of expired ones, can’t wait to try them out!
Robin,
Vitamin C speeds up the development and for me, reduces fog. It also adds more contrast. If you try without Vitamin C, you have to develop at least 30 minutes, or you will get very, very thin negatives.
Thanks, that wasn’t clear at all to me, great
Hello,
where contains the Caffenol developer silver? And does this also work with Dia films? Because I ordered some super 8 cartidges that expired in 1988. before i give them away for developing i thought i could cut off a small piece of the film, develop it in caffenol and see how the film comes out. Because I don’t want to waste my money on developing a unusable film that shows no results. Thank you
Felix,
Caffenol does not contain Silver, But color FIlm contains silver haloids, which will develop in caffenol.
It will also work with Dia films, but the negatives will be very, very dense. But scannable.
cheers,
