    Bad coffee

    Hi

    I was trying out the wonders of Caffenol but with failure as a result.
    Can someone tell me where I did wrong?

    Here is the details:

    • Tri-X rated at ISO 400
    • Developed in 300 ml. water, 4 teaspoons of instant coffee and 2 teaspoons of washing soda
    • Developed it for 30 minutes @ 68F
    • Agitation: 1 minutes continuous, 10 sec. every minute.
    • Washed the film with water
    • Fixed it in Acidofix
    • Washed in running water for 20 minutes


    The negs came out VERY thin. All I could see in the film was a few highlights. The start of the film, which is exposed when loading and unloading the camera, was not black (as it was supposed to be) but light grey.

    The film was, as I see it, heavily underdeveloped.

    Please tell me where I went wrong....

    Greetings Morten

    PS.: I guess it's the punishment for messing 'round with other stuff than Hot Rod.

    The recipe i've seen calls for 8 oz of water, which would be more like 225-250 ml of water, so if you used 300, then it was probably diluted too much.

    Sorry it didn't work out for you.

    Hello,

    I don't think you did anything wrong. The only time I read of using coffee as a developer the article indicated that the negatives were extremely flat and thin. It was simply done to prove that coffee could develop film.

    IMHO,
    Rocky

    XTOL and drink the coffee? Morten would probably rather put the coffee in the XTOL and drink selenium toner if he was barred from using Rodinal.

    Rate the film at 200. It's hard enough to get an EI of 400 out of Tri-X, even with something that's supposed to develop film.

    I haven't tried coffee-as-developer, but has anyone tried espresso instead of instant? Maybe with a twist of lemon rubbed on the edge of the tank?
