Another Caffenol test from a while ago:

Developed this film together with a Kentmere Pan 400 film in our Caffenol-C-L recipe at 22c and stand developing for 50 minutes this time.
Next time I'll go for 55/60 minutes with the XP2 Super 400. The results are okay but a bit dark, while the Kentmere film was perfect.
