    I posted similar information earlier in the newsgroup.
    It is a commercial announcement that Adox Fotowerke, Inc. is now selling a
    film-developer combination called Adox Bluefire. It is the film and
    developer formerly sold by Bluefire Laboratories which has been discussed
    here in the past. I believe this newws will be of interest to both
    darkroom-oriented newsgroups, and I hope no-one is offended or feels I am
    misusing the usenet.

    I would be glad to answer commercially-oriented questions by e-mail (dfoy at, and non-commercial questions here.

  2. I thought Efke was manufacturing Adox formulations. Adox is still in business?

  3. H&W Control was similar in concept. Remember that stuff?

    No. The photographic holdings of the Schleussner family, Adox Fotowerke Dr.
    C. Schleussner GMBH, were sold by Dr. Schleussner's heirs in 1962 to DuPont.
    The family retained their holdings in medical diagnostics and industrial
    coatings, and are still a significant force in European industry (and, as
    partners in the original South German Radio Network, in European culture.)
    DuPont eventually ended their photographic business and by 1985 the
    trademark had been abandoned.

    The new company is unrelated to the original company and has revived the
    trademark. The new film is unrelated to the original Adox films, which
    DuPont licensed to Fotokemika, and who continue making them today.
    Fotokemika acquired the technology but not the trademark, so they have
    always sold them under their own trademark, which is Efke (*F*oto *K*emika,
    "Eff Kay").

    Adox Bluefire HR developer concentrate is based on the H&W developer. It
    uses a more stable form of phenidone and has a longer shelf life, but gives
    sensitometric results that are identical. H&W's film was Agfa Copex Pan
    Rapid AHU, EI 80, a microfilm. Adox Bluefire is Tura Pan Line, also EI 80,
    also a microfilm, but different from Copex.

  6. Yes, I do... It was popular to a subset of photographers when I was in
    HS (71-74). I was a Panatomic-X in Microdol guy and my buddy was a H&W
    Control freak.

    As I remember it, H&W Control was some type of microfilm emulsion and,
    when run through the H&W Control developer, it was a good pictorial
    film. It was a little picky about temperatures and concentrations of
    the developer. It took a little fiddling to get it to work right.
    (Sounds kinda like Tech Pan now, huh?)

    At the time, my funds were so limited that I didn't dare try anything
    that I didn't know worked so I stuck to what I knew. My buddy, however,
    used it, figured it out and got great results.

  7. Ok, how about:

    1. What is it?

    2. What sizes is it available in?

    3. Where do we get it?

    4. What can we do with it?

    5. What are its good points.

    6. What are it's bad points.

    Thanks for the questions. I've annotated your post below.

    It is a film which, when developed in the matching developer, can be
    enlarged to extremes with little or no apparent grain. For well-exposed and
    processed negatives, grain should not be apparent even at the degree of
    enlargement where lens resolution starts to fall off. The film is a
    microfilm, which ordinarily would give high contrast (stark black and white)
    but the developer gives it pictorial gradation. There are examples posted at
    the commercial web site

    The closest comparable product is Tech Pan. They differ in that Tech Pan is
    on a very thin base, while Bluefire's base is the same thickness as ordinary
    films, and they handle differently in the darkroom; Tech Pan has extended
    red sensitivity, and Bluefire has normal panchromatic sensitivity, so they
    respond differently in most lighting situations; and the two films have
    noticeably different image qualities, such that most photographers will
    prefer one or the other. The benefit of having the new film available is
    that photographers now have more choice.
    35mm, 24-exposure rolls. Soon, 30.5m bulk rolls.
    The only current retail dealer is the above commercial web site. It is not
    possible to predict how many dealers will eventually carry it, but
    presumably by this time next year it will be available from several sources.
    Quantity buyers should contact .
    It has three main uses:
    1: as a microfilm, used to copy documents, it is exposed at EI 100 and
    developed in any ordinary high-contrast chemistry like Dektol or D-19;
    2: as a technical film or lith film, for copying, masking, photo
    restoration, etc.; the technician would choose exposure and developer based
    on the job at hand. This kind of work invariably requires the use of filters
    and considerable experimentation, no matter what film is being used.
    3: as a pictorial film when its image properties meet the photographer's
    aesthetic goal, or when extreme enlargement is contemplated. This requires
    the matched developer or a similar developer (POTA, Technidol, Formulary
    TD-3, one of the Maco developers, etc). and IE 80 is a realistic speed for
    most purposes.
    Little or no grain when enlarged to extremes. Most of its benefits come from
    pairing it with the right developer:
    High speed for films of its type (EI 80 when developed in the companion
    Excellent tonal range when developed in an appropriate developer as noted
    "Normal" negatives print well on no. 2 grade paper (I know "normal" is hard
    to define, but I hope my point comes across).
    Responds well to curve manipulation in programs like PhotoShop.
    Less exposure latitude than ordinary pictorial films. This was a problem
    with the original film/developer combination of the type, which was H&W
    Control, circa 35 years ago, when careful hand metering was a requirement.
    It is less of a problem now if you are using a camera with very good
    internal metering.
    Like all fine-grained and relatively slow films, it should be used carefully
    to avoid excessive contrast.
    For best pictorial results, needs longer than normal development time (15
    minutes is recommended).

  9. Tura in Dueren, near Aachen? Tura doesn´t make own emulsions/films for
    a long time, but repackages Agfa APX and papers.
