Transparencies and Jobo

    Last night I processed 4x5 transparencies in my Jobo CPE for the first time.
    I've processed a lot of 35mm slide that what but it was the first time for
    4x5. I ran into an interesting problem. Using a 2509n reel the two out sheets
    came out of the tank blank. The two inner sheets came out fine.

    This has me very worried. While it's not beyond my abilities to screw up the
    exposure of the two sheet. It seems to me the odds are against me putting
    them both on the outside of the reel. The lettering from Kodak developed out
    ok.

    Has anyone here processed 4x5 transparencies with the 2509n reel? If so
    did I simply beat the odds and put the mis-exposed sheets on the outside or
    is there a bigger problem?

  2. Maybe not enough chemistry ? Have you used the reel before, maybe your not get flow between the
    sheets or through the reel. Or like you stated my you just got "lucky" with the exposure.

    Why would transparencies be more of a problem then something like B&W
    negative sheets? On the suggestion that it's not enough chemicals the inner
    sheets are the ones that would get hit by this. Right?

    I put 6 sheets of B&W film on my reels. Some times 4. The only problems
    are the ones my skills with the camera created.

    I just can't see how the two outer sheets would get screwed up.

  4. I will lay good odds that the second film holder
    you loaded was unexposed. The holder you did
    expose has not yet been developed -- it's in
    your equipment case, lying on the grass, etc.

  5. If the two blank films were not mottled, or obviously stuck together, then
    they likely were not exposed when put in the Jobo... How's about you loaded
    that dark slide with the two sheets backward?!?
    Now me, I've never done that... nope... not me... never... <coff>

    This is what I think as well. I have processed 4x5 transparencies in 2509
    and it is not any different than B&W or color negatives. The fact that edge
    printing came out fine, indicates that there was no problem with chemicals
    or processing. Just look at other holders and try to figure out where the
    exposed sheets are.

    Since the lettering came out fine, those two were never exposed.

    I didn't think that there would be any difference between the trancarency and
    B&W film and I've developed hundreds of sheets of B&W. I'm sure that I managed
    to mess something up. It wouldn't be like I've never put the readyload
    in backwards or forget to pull the sleeve out beofre making the exposure.

    I just thought it was more then a coincidence that the two readyloads I didn't
    expose right were the two outer negatives. Oh, well. Maybe I just found
    another way to sccrew up an exposure. :-(

  9. Just means that you have, through sheer dint of effort and trial, managed to
    become more advanced than the rest of us, who can usually only manage to
    mess up one sheet at a time...

    WOOO HOOOO, I just processed six sheets of transparencies with my Jobo and
    not a black sheet of film amoung them!! While not surprised that I managed
    to mess up the exposure of half the exposures I made. I do find it interesting
    that that the two blown exposures were the two outer sheets on the reel.
