Just kidding about Holmburgers He's got better things to work on there than my silly stuff. And it ocurs to me I wouldn't know know how to properly use a microdensitometer even if I had access to one.
Just one correction of a typo in one of my "questions" (which Mr. Bill has already tried to answer) in case it caused any confusion:
"Why would the developing time for AH-15 be longer shorter than for AH-1 if the only difference between the two developers is a lower Metol concentration?"
Obviously it should have read "Why would the developing time for AH-15 be shorter than for AH-1..."
