I am guessing the subject line caught everyone's eye.
My wife was at a film archives conference recently in NYC and one of the books she brought back was a collection of reproductions from newsletters published by what you might call "alternative" filmmakers (motion picture). One of these articles described a method of developing 16mm b&w motion picture stock in urine. Well, to be precise, in D-19 and urine - it was the same method of mixing except instead of water, one used urine.
The author recommended using urine collected the morning after an evening of drinking (perhaps this calls for a new kind of photographic outing, followed by a darkroom session). The author claimed that the film came out pretty much the same as with regular D-19 and water, but with an additional ... "sparkle." Somethign to do with pH.
The part that truly grossed me out was heating up the urine on the stove to the correct temperature for mixing in the D-19. I suggest you do it outside or, at the very least, don't do it in my kitchen.
I think that this formula should be called P-19.
I swear to you that this is true and will send scans of the article to whomever wants to read it.
