Great. I'm trying it.
I had a bit of trouble getting the ingredients, so this may help:
Tesco sell Dri-Pak washing soda for about 60p a pack. Vitamin C powder is available at Holland & Barrett for £5.99. You don't need Vit C to make it work, although it apparently reduces staining on the negs so it's worth using. You might have to use Google to find the correct dev time for your film (it takes longer than you might expect). And don't be tempted to drink the developer
I'm doing a roll of FP4+ this evening. I'm going to try the straight (non C) version first because I rather like the stained look - although how stable the stain is, I have no idea. I think vitamin C is also supposed to reduce the development time somewhat and I can get it direct from Sigma/Aldrich via my girlfriend (she's a research chemist). Based on what I've read on APUG ~30 mins for Caffenol or 12ish for Caffenol-C seems about average for 100ish ISO. Does that sound about right? I'm told it really stinks too.
Well from what i've read you can use just vit C, no caffeine. It might smell better as well! I'll try and find the link

That puts mine to shame. Must try the 'value' coffee.
Could we somehow merge the Caffenol and coffee machine threads? I'm sure hand-ground espresso would give superior bokeh.
Looks really good John - silly question - does the coffee-soup literally 'brown' or sepia-tone the neg?
