    Developing in Urine

    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.

    I thought D-76 smelled a bit like urine when I was mixing it up for the first time last week...

    This sort of thing seems to come up on a regular basis...

    And when you say the images have that extra "sparkle" are you sure it shouldn't be "sprinkle"?

    WYSIWYG - At least that's my goal.

    In Grant Haist's book "Modern Photographic Processing" he describes the use of both urine and wine alone for development. I guess using the combination of urine after drinking wine is not so far fetched or such a stretch as the tannins would pass through the body to a certain extend, and the byproducts of metabolism are related to developing agents.

    I wonder if mouse urine would work. We have had a persistant family of mice digging under the porch. I plugged the hole with concrete the other day and found the day after that the mouse, in his frustration, had left claw marks on the concrete and then had urinated on it. There were visible claw marks and 2 or 3 small yellow puddles on top of the new concrete. Should I collect a sample? Squirrel urine would probably be better due to their diet of acorns. All of the tannins would be great.

    Never mind the mice---find a horse....it seems that horse urine contains catechol (ok, so does human urine) with the added benefit that you can make a batch large enough for deep-tank 8x10 processing with just one go.

    Gonna need a lot of wine and some oats, though.

    Yeah, but if you process important film in this type of developer and it doesn't come out ... well, then urine trouble!
