    Are you not tray developing under a safelight? You would be able to see it developing and not stop at 2:40 if it wasn't long enough.

    Otherwise, did you expose the wrong side of the paper? ....It's happened to me more than I would care to admit.
    I'm not tray developing because I don't have a permanent darkroom at the moment. if at 17 degrees 5 1/5 is enough then at 20 degrees it should be around 3 minutes right? give or take.

    so I'll try more developing time.

    Another problem I have is that I can only shoot one, process one, shoot one - process, so it all takes a long time. anyway, nevermind.

    Sounds like you are on the right track.

    Just don't do what I did last night or the other day. With these low concentrations things can go wrong. I made both mistakes...

    1. Stir the developer to completely mix it.
    2. Don't wash out the mixing vessel after adding the 1 part of concentrate.

    Yup I meant to develop in Dektol 1:9, and instead I carefully measured 1 part Dektol. Asked my wife what's 9 times 3. She told me 27 and I carelessly rinsed out the beaker, added 9 parts water and saw it was short of the 30 ounces total, so I added 3 more ounces of water.

    I developed a roll of film for 5 minutes in 10 parts water last night.

    the positive was inverted in photoshop for now, but I'm gonna try making a positive in camera later.
    the final working solution was:

    dev: 1:100 rodinal, 20 degrees, 5.30 minutes
    stop and fix to manufacturer specs.

    so a couple more questions, how do you stop them curling? and what's the best way to meter making a positive? bearing in mind I'll be using a camera instead of a "real" enlarger. Is it ok to just meter as if I was simply taking a picture?

    Just a bit curious; how did you check exposure on your digital (that has a minimum of ISO 100) against papers that are... what.. ISO 3?

    I tested at iso 100 and then worked it down in whole stops from there
