Hi Richard - Which site did you get the Darkroom Cook book from? I've tried
three, but my virus protection recommends keeping clear of them. Thanks - Brian

Hi!
I like to roll my own. I had great fun mixing the Rodinal according to
the outline given in The Darkroom Cookbook.
The third edition is available on line.
I mixed a liter about four years ago into two bottles. The first is
almost gone.

After I sent this I began to wonder if it made any sense and also if
anyone had actually done it. However, the name Tylenol is derived from the
chemical name
N-acetyl-para-aminophenol So, perhaps.

I haven’t thought about chemistry at this level since 1968, so it’s not
obvious to me why this substitution would produce similar results and merit the
same name. Does anyone have a simple explanation? At first blush, when the
developing agent is changed, you can’t sensibly call the developer by the same
name.
