Possibly Bernard and thank you for your comments, but my previous tests on Medium Format have shown that films processed at box speed in the Caffenol CL have been very dense. I use the frame numbers as a guide as to whether or not the film is over/under developed and have adjusted the Caffenol CL time to suit, I then adjust the speed of the film to give me a negative with a full range of tones. Typically with medium format this has been best with a doubling of the box speed.
As this was my first 4x5 there is bound to be a period of testing going forward and I will eventually settle on a film speed to suit but I am very pleased with this first image and there is a full range of tones on the negative including in the dense shadows on the RHS.
Fantastic! A lot better than my attempt at the Taco method, now I use a Unicolor Drum and rotating base for all my 4x5 processing.
