Thank you Conrad, Mike and Glen.
I also want to ask your advice for using Rodinal stand 1+100 for 1hr. That seems to be some magic trick for any occasion when someone asks: "I'm in doubt how to process this particular film". Sometimes one even asks how to process "This unknown type of film".
The often seen answer is as I already mentioned: Rodinal 1+100 stand for 1 hr.
People get good results with any kind of B&W negative films as well as with cross-processing C-41 using that magical formula.
Why is that formula so popular and safe to use for almost anything?
