    Hi All,

    Have just started using Forte Polywarmtone FB paper, using Agfa neutol
    warmtone dev, however I cannot find any instructions as to what filtration
    to use
    for different grades needed. I have a Durst 707 enlarger.
    Can anyone please help with the filtration for grades 2 -3 - 4 - 5

    Thanks in advance

  2. Lofty spake thus:
    I'd be surprised if a set of Ilford filters didn't work admirably.

  3. Does Forte recommend any particular brand of VC filters?
    If so you may be able to get the corresponding filter
    settings for Durst. Kodak had such charts on its paper data
    sheets which I think are still on the web site. I haven't
    checked Ilford data sheets but the use of color heads for VC
    printing is so common I suspect they must.
    Each VC paper is a bit different so using settings for
    one kind of paper for another may not result in the correct
    grade, spacings, or exposure compensation but they will be
    at least in the ball park.

  4. Hi,

    I don't know that starting with Forte paper is such a good idea. The
    plant has been shut down since February and there is no more Forte paper
    being made, unless the paper has been resurrected by another company.
    There was talk that Kentmere might be interested but I haven't heard if
    that went anywhere.

    Same for using Afga products. I used to use Agfa Neutol warmtone until
    Agfa stopped making photo chemicals, paper and certain films. Again,
    has something changed???

    Cheers,
    Bogdan

    This is a serious problem now. Agfa is simply out of
    the photographic materials business and Kodak has
    discontinued papers. That leaves Ilford and to some extent
    Kentmere. Both Agfa and Kodak had extensive laboratory
    facilities and good quality controll, especially Kodak. I
    think Ilford still has some lab facilities and pretty good
    QC, not sure of Kentmere, but the small European
    manufacturers probably are only following formulas and
    techniques inhereted from larger companies. Its hard to know
    even which brands are actually made by the company who's
    name is on them. For instance Bergger seems to be rebranded
    material from someone else. Both Ilford and Kentmere have
    traditionally made paper on a contract basis. Ilford
    announced at one time that they would discontinue the
    practice but it appears that they have not. The problem is
    getting any real technical data on these materials. This was
    never a problem with Kodak, Agfa, or Ilford. Ilford seems to
    be the one remaining "major league" company in the paper
    business. I do not include Fuji because they do not sell
    their B&W papers outside of Japan.

    Isn't there some way around that? Find a decent agent in Japan to ship
    it to us? Anyone here living in Japan who would like to negotiate a
    shipment of a few thousand sheets?

    BTW, Richard, regarding quality control I find so many people today who
    for the purpose of maximizing capital will bypass QC, believing that the
    necessary refinements of the process and components has come to near
    perfection. They have no freaking clue as to the critical factors.

  7. Probably true. The trouble is that publically traded
    companies worry much more about stock market performance
    than about what they make or do.
    I suppose there are ways of obtaining Fuji B&W paper
    outside of Japan but it sure would be nice if I could run up
    to Freestyle and just buy it off the shelf. It s reputedly
    excellent stuff.

    I purchased my Forte polywarmtone from a guy who went 100% digital. £5 for a
    brand new box 16x12"
    great deal. I dev'd it in Agfa neutol WA results were fab.
    Kentmere is still being made in England

  9. Sounds like a very good deal. I've had good experience
    with Kentmere BTW. They make some good warm tone paper. I've
    never been sure what is in Neutol WA, Agfa used some pretty
    exotic developing agents but there are other public formulas
    for warm tone developers in case you want to try mixing your
    own.

    I'm not sure whether you still need this, but I've got a copy of the
    usage instructions for the RC version of this paper if you're
    interested? Includes grade information.
