In response to the request for the Rodinal formula: there are many that have been published over the years. I give the oldest one I could find in my article "Appreciating Rodinal" at http://unblinkingeye.com/Articles/Rodinal/rodinal.html. I have never tried it--I just provide it as a reference point for the article. (If anyone decides to try it, be damn careful with the sodium hydroxide.)(posted 8418 days ago)
