B/W Transparency

Discussion in 'Darkroom Developing and Printing' started by Roman J. Rohleder, Jul 19, 2003.

  1. Yes. Foma from the Czech Republic has both a bw slide film named
    Fomapan 100R and a Developing Kit for home processing.

    It is available in Germany through www.fotoimpex.de and in the USA at
    their partner, "J and C", www.fotoimpex.us (if not now, it will be
    available, as the enhance their product portfolio).

    The Foma kit is cheaper than the Kodak stuff.
    You can mix your own kit from scratch. Recipes are available all
    around the net (and in the google archive of this newsgroup) - but use
    the ones with potassium permanganate in the bleaching bath.

    One hint:

  2. Hi, Folks:
    Is there any other B/W transparency in the market other
    than Scala and T-Max Direct Positive Process?

    I tried to process Kodak T-Max CN and Ilford XP2 in
    E-6, and I got amazing result. T-Max CN turn out brownish
    image, and Ilford XP2 turn out greenish image.

    They looks amazing, but still a bit less than what I want.
    I'm looking for some result like Scala or T-Max Direct
    Positive process.

    Is there process can have similar result but with easy access?

    Thanks a lot for your time and help.

    Sincerely
    Dysan C. Tsai

  4. FWIW, Kodak Fine Grain Release Positive has an emulsion
    very similar to graded enlarging paper. Its contrast can be
    varied over a fairly large range by choice of developer and
    time. Its slow enough to be easy to handle. Its processed
    for the most part just the way printing paper is done.
    Reversal processing requires some tuning of the first
    developer to the particular film. The first developer has a
    halide solvent in it, the amount varies with the film.
    One problem is that nearly all 35mm negative films have a
    gray pigment in the support to reduce halation and
    light-piping. Unlike anti-halation dye the pigment is not
    decolorized or come out in processing. This reduces the
    brilliance of transparencies made this way.
