Agree 100%. In fact, in additon to the specific tech publications/instructions for specific materials, both Kodak and Ilford have a variety of very good papers available on their websites about testing, process control, negative contrast, printing etc. I often direct people to these in threads but Ilford and Kodak usually get drowned out!
Actually given a few other recent threads I'm thinking of posting a thread with links to all these documents. They are excellent resources for people starting out.
