This was taken on Rollei RPX 100 (Exposed as 200ASA) I used Caffenol C-L with Semi stand development .That's 50mins at 20˚c with agitations for the first minute then 3 at 2,4,8,16 and, 32 mins.

I must say that these were the best negatives I have had so far from Caffenol. Negatives scanned with my epson V700 with silverfast 8 SW.
Camera used was a tripod mounted Hasselblad 203FE with a CZ Planar 110mm f2.0 mounted on E56 and E32 Extension tubes.
