The first time i heard about Caffenol was in March 2010 when Reinhold started his Blog. At first I thought this would be a nice experiment and very cool to mix up your own developer by ingredients that can be found in most of out households. So I started my first trials with Fuji Acros 100 and Caffenol C-M. The results were pretty good and I decided to give the Rollei Universal200 a try, a film with beautiful fine grain and impressing sharpness.
That said and done I first tried the Caffenol C-H recipe, which ended up in very dense and foggy negatives with almost no picture to be seen on the film. I tried several shorter times, but the negatives stayed very dense and kept foggy. So the time had come to ask Reinhold for help and I sent him a few rolls for his own trials. Sadly that Reinhold has stated, that the Universal200 refuses to get developed in Caffenol. Though you can get a picture with a good scanner like the Nikon 9000 ED being able to read also high densities, these negatives won't be useful for printing in your darkroom.
