I recieved Jobo procesor and I have idea to calibrate my negative process for Zone system - Bobrb

Many thanks for your question bob, and Ralph for your timely answer. There has been so much on APUG lately which mentions this topic without adequate explanation - I need right now to understand the process of calibration from film to paper. I've downloaded the files from your website link and will walk through it. I also have truly enjoyed your book Ralph "Way Beyond Monochrome", a lot of the topics are so relevant for me today as a darkroom user. Again, thanks.
