    How big are these reels? How many inches/cm across? I've picked
    up a small print drum [1525] that I'd like to also use for film but the
    thing looks too small for a film reel. I know Jobo 1501 are supposed to be
    smaller then Paterson reels but this is less then 4" inside.

    I just measured one of mine, and it's 9cm in diameter.

  3. Nick: What are your plans for the Jobo and film development? What size
    film are you using?

    Thanks that should fit just fine.

  5. Please, don't answer this question.

    This guy Scarpitti is the sleaziest dirtbag of a D.A. you'll ever see. He
    wants you to cop to the rap of doing 35mm film in a Jobo, whereupon he'll try
    to plea-bargain you down to conspiracy to commit violent agitation (with
    malicious intent to destroy "edge effects"). As your lawyer, I implore you
    *not* to answer this question.

    It's fun to demonize the neo-cons and rejoice in their discomfiture, but
    don't make the mistake of thinking US foreign policy was set by Norman
    Podhoretz or William Kristol. They're the clowns capering about in front of
    the donkey and the elephant. The donkey says the UN should clean up after
    them, and the elephant now says the donkey may have a point. Somebody has
    come out with a dustpan and broom.

  6. I do not know about Nick, but I process all my 8x10" film in Jobo 1502
    reels. It is true that dodging while printing is difficult, but how else
    do you remove the pressure marks resulting from getting the sheets into
    those tiny reels? Since I cannot afford a Jobo film tank, I put those
    reels into my blender (which I have painted black) and buzz for 7:12.123
    after adjusting the room temperature to that required for the film.
    Color film is difficult in the winter.

  7. Yes, I suppose I could look up what Jobo 1501 reels are, but I didn't
    have time. My point would be that hand processing of 35mm film is

  8. You are absolutely right. When it really matters, I cut up my
    36-exposure rolls of film into separate 1.5" long strips and develop
    them one at a time in trays (5x7 stainless are best). I use 12 different
    film developpers- Dr. Beers seem best except when Amidol is called for.

    I don't know if anyone answered the rest of the question.....

    In order to convert a 1500-series print drum to a film drum you'll
    also need the plastic center core for the reels plus a funnel rather
    than a cup inside the cap. Details can be found somewhere in

  10. Very easy and comprehensible. The only real disadvantage with this method is
    that you will double your film consumption... or how do you cut the film
    exactly along the borders? It seems to me that this method only works if
    you take every shot twice and cut the strips 3" long, so you are guaranteed
    to have one untouched negative on each strip.

    Zone system _is_ possible in 35mm ;-)))

  11. No need to take two of everything. Just count the sprocket holes and
    always load the film into the camera exactly the same way.

    The 1500 series tanks have a funnel in the lid, at least all that I own
    have it. If you plug the tube of the funnel with a rubber stopper or
    the Jobo supplied plug, it can be used for paper and film as long as it
    used on a Jobo processor with a lift.

    It seems the funnel and center core from my 2500 series tank fits.
    Considering I've got a 2500 tank that I've been thinking of converting to a
    print tank and now a 1500 series print tank that I'd like to convert to film
    everything is coming together-))

    Nick Zentena, Sep 24, 2003
  14. Right, I didn't think about that. An alternative would be using
    a camera with a builtin film cutter (IIRC some Exacta model has
    one) and cut the film directly after shooting a picture. One could
    easily remove the strip in a dark bag and put it in a light-tight

    No excuses: a real 35mm Zonie would develop in the field.

    If you're doing 120 film, beware that the 1500 reels can cause
    development/density defects along the edge of the film because the
    smooth spiral overlaps the image area. 2500 reels have ridges to
    prevent this.

    A bit of both. I was just hoping to use the 1500 type tank and reels for
    C-41 processing. The tanks use less chemicals in inversion mode. I'm perfectly
    happy using the 2500 tank on a rollerbase but I'm not sure how well it'll
    hold the temp. I really should test. I basically got the tank for free
    [Wonders of Ebay] so if it's only usefull for prints I can live with that.

    Does this show up in both inversion and rotary mode?

    Yes it does.

    I've never noticed a problem. Could you post an example somewhere?
