turner reich and contact print problem

  1. Hello All, I have two seperate questions. First, does anyone out
    there know the filer ring size for a Turner Reich convertable? It's
    the series 2, with an 18" and 12" focal length. I need to know so I
    can order a step up ring for my 67mm filters.
    Also, I am having a problem with these small white balls on my
    double weight contact prints(8x10). I never have it when I print with
    platinum or azo so it must have something to do with the double weight
    fb paper. I have tried thick glass and it still happens. Any recipes
    for success would be greatly appreciated.

    <p>

    many thanks

  2. Eck, try moving farther away from the driving range, this should take
    care of the small white balls!
     
  3. thanks Ed I'll give that a try. No, it's those little white dots and
    they appear only in clear areas.

  4. Problematic paper, maybe - try exposing a paper to full room light
    and developing that to see if you still get spots on it. Maybe you
    had some chemical in the room that fixed out little spots on the
    paper. Cheers, DJ.
     
  5. Eck, are you using an acid stop bath? If you are, and it is to
    strong, it can cause air bells to form under the paper emulsion which
    burst and cause the white spots. Also lack of sufficent agitation in
    the developer can allow air bubbles to sit on the developing print,
    these act a resist and no developement occurs in the places.
    I also have a Turner Reich, mine is a triple, convertible lens and I
    will check it to see what filter size is being used. Will respond
    tomorrow.
