Canon Eos 3 - Canon EF 24-105 F4 L IS USM
Ilford Ortho Plus 80 developed in our Caffenol recipe, Caffenol-C-L at 22c and stand developing for 50 minutes

How do you make this coffee developer? And how do you determine development time? Trial and error?

Amazing how good the tonality is with a developer so basic.

It would be fun to try to make a caffenol developer from scratch. So far, I have only used DD-X, Ilfosol and Rodinal.

@Ulrik, It's just a mixture with Coffee, Washing Soda, Vitamin C and KBr (Potassium bromide)
I started with a recipe from the Caffenol cookbook & bible :www.caffenol.org/2012/11/27/the-caffenol-cookbook-bible/
And after some testing and trying I ended up with a recipe for a Caffenol-C-L recipe that works for me.
Being a bit lazy I like this C-L variant. 😉
Just poor the developer in the tank at about 22c and leave it for 50 minutes (stand developing) And this works for almost every film I use
(Kentmere, Ilford, Fuji and a few Rollei variants)
Some films don't like the Caffenol developer So I do have some Ilfosol 3 for those

@TheDavinator: Thanks as mentioned above, the Caffenol-C-L recipe is a nice developer for many films

Hm - interesting. Thanks Photobygms. I might delve into that - I think we have some KBr at work :)
