Any thoughts (anyone) on stand development as compared to with more
frequent agitation when using Rodinal with film? Thanks.

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 Smith

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.
