    I have always developed my APX100 and APX100 films in HC-110 delution
    1+31 for 6:30 minutes @ 20C. I was pleased with the results. (The
    official time was 6 minutes).

    I now have the new APX100 and APX400 film. Has anyone the development
    time for the APX400new in Kodak HC-110 1+31?
    The sites that I know (digital thruth and the German Phototec) don't
    give a development time for this new films.

  2. The reports I've been seeing on photo.net suggest the new film requires
    slightly more time than the old, but I don't recall exact figures
    because I don't use Agfa films (Kodak is highly available here in the
    USA, often recently expired at bargain prices -- and I've never used any
    other brand of B&W film, in 35 years, at least partly from habit, though
    I have to say Tri-X has done everything I could possibly ask of a 400
    speed film).

    I'd be inclined to do a clip test -- shoot a 36 exposure roll of a
    "normal contrast" subject, metered the way you normally do, then (in the
    dark) clip off a foot or so (30 cm) and develop that, examine the
    results, clip another piece and develop for a slightly different time,
    etc. With the original times as a starting point, you can probably
    arrive at your preferred time with one roll of test frames (36 exposures
    is five feet of film, or about 150 cm; 30 cm is plenty for a clip test).

  3. Strangely, Ilford films are less expensive here in Canada (at least at my
    dealer) than Kodak films are, and I'm glad for that because I've come to
    appreciate them. As good as Kodak films are, you should try the competition
    a bit. :)

    Frankly, I question Kodak's commitment to silver-based imaging and that's
    another reason why I give money to Ilford and Fuji and not much to Kodak,
    but that's a topic for another thread.

  4. In fact, Ilford films are the same or a little less expensive here, as
    well, and Agfa quite a bit less. I've just never had the time to spend
    testing an unfamiliar film when Tri-X and TMY do the job so well for me.
    In addition, Tri-X has the best latitude going, and pushes better than
    any other film with the possible exception of the "super high speed"
    films (800 to 1000 true speed, but designed to be pushed to 1600 or
    3200). You can't begin to get the same level of push (if you need it)
    from HP5+ that you can from Tri-X.

    I mention the prices because, by buying recently exposed film, I get
    film that's never let me down for prices comparable to fresh Agfa. I
    don't think I have a roll of film anywhere in my house right now that's
    not expired.
    Well, if enough people give their money to Ilfor, Fuji, and Agfa instead
    of Kodak, we're certain to see Kodak drop silver based film -- because,
    like any business, if it doesn't produce a return commensurate with
    investment and operating cost, it'll be sold off or closed down.

  5. Er, well, I rarely by film that's been recently exposed -- I meant
    recently expired, of course...

    by buying recently exposed film, I get
    That's a unique ability I've never been able to coax out of MY films....

  7. While that's certainly true, if I were to buy more Kodak and less Ilford and
    Fuji, I'd encourage the latter two firms to abandon silver photography, too.
    I can only consume so much film. :)

    You're right about Tri-X's pushability. It is definitely more pushable than
    HP5 Plus, but I usually shoot films at their rated EI and at this index I
    prefer the Ilford product. I do buy the occasional 100' spool of Tri-X and
    develop it in PMK, a developer in which it performs extremely well.

    How do you know that, if you've never used anything but Tri-X and TMY?

  9. I can read.

    And I have used other films -- I used a lot of Verichrome Pan 620 in the
    late 1960s and early 1970s, and I've shot more than a few rolls of
    Plus-X at various times, as well as a couple rolls of Fuji Acros 100.
    I've just never used an Ilford or Agfa film, and don't see any incentive
    to do so at present.
