    uneven dev with jobo cpe2

    hi,

    lately ive been getting a lot of uneven development with mmy jobo cpe2. i think the film is touching in parts on the reel too which is strange as it is definitely all threded on correctly. mostly its just the tail of the film which i think is curling down and touching film below. does anyone know whay this could happen at all?

    can you give us a few more details - what film format, reels and tank used?

    a couple of thoughts - not enough chemistry, processor not level..and are you pre-washing your film first - most important thing for even development in my experience..

    Except for XTOL which Jobo explicitly states not to prewash film.

    As posted above, please give us the details: film, developer, temperture, times, volumes of chemicals, tanks, reels. Every one of those matter.

    i ahve used various films-kodak ektachrome epp, fuji reala, , prove, all 120 format. dev is rollei digibase kit at 38.7oC for 3:15. i use 250ml of chemistr in a jobo 1520 tank using a plastic jobo reel. i leave the jobo for at least 45 minutes each time before starting the dev process. i always start with a presoak but im wondering if that is causing damage.

    Dear wilfbiffherb,

    A picture of the problem might help people contribute possible causes.

    Please provide
    a scan of the negatives
    tanks and reels
    developer, stop bath, hypo: type, dilutions, times, temperatures
    That way we can help you converge on what the problem is and then find a solution for you much faster.

    if you look at this image you can see the top shots are fine but lower down the film is almost opaque. i checked when i was taking it off the reel and this is area of film came form the inner part of the reel.
