We recently had a discussion at Apug if pure arabica coffee without Vit-C would do any development, one guy reported that he had no development at all with arabica coffee. We can read at differe...

 Hi coffee users and abusers, good news about film and Caffenol. The "original" Rollei RPX 400 is back! The RPX 400 from the very first production was a great film with good pushing b...

Often it's not easy to get clean negatives without spots, drying marks etc. Fernando e.g. asked what he can do to get rid of these spots. Instead of a reply as a comment here my thoughts about av...

Happy new year 2014 everybody. Medium format quality with slow technical (micro) 35mm films and Caffenol-C as a great and cheap developer compared to the dedicated and expensive soups? Yes, w...

Microfilms are a little bit delicate to process, because the extremely thin emulsions are very contrasty as they shall be regarding the original purpose. Anyhow, for pictorial use we don't need ...

After a few more results with Caffenol-C-F I have to state that compared with my other Caffenol receipes this is a weak developer giving thinner negatives. It has less Vit-C and the sulfite is a...

Hi guys, something new after a long time. I had lots of fun with Caffenol-C developers in the past and wanted to try something new for me. Caffenol-C and it's many variants are not real fine ...
