Kodak TechPan - not difficult!

Discussion in 'Kodak' started by Claudio Bonavolta, Jan 3, 2005.

  1. I like it for landscapes and portraits, and too, appreciate its tonal range.
    If you use the processing method Kodak indicates in their technical documentation, it's more
    complicated than the classic one:
    you have to fill the tank with the developer alone, then, in complete darkness, load the reels,
    insert them quickly in the developer, close the tank and start the "shaker" agitation every 30".

    I've read on the web that some report good result using rotation which, I thought, was unusable with
    TP. So, next time, I'll give it a try.
    With all TP characteristics together, probably nothing.
    For fine grain and sharpness, TMax 100 and Acros 100 are not that far but they don't have the pretty
    unusual tonal balance and extended red sensivity TP has.
    For other use than pictorial photography then you have to switch to other special-purposes films.
    I bought three 45m rolls and started to load my rolls again ...

  2. I have no idea.

    Follow the instructions and it works. No ifs, no ands, no ors, no
    buts.

    Tech Pan complaints can't be a reflection on the film or its processing,
    and that would seem to point to those who find it "difficult" as being the
    source of the problem: "The right time, the right temperature, the
    right developer -- Oh man, what a pain!"
    Stock up with 30 years worth?

  3. Greetings;

    I've just developed the last of the monochrome films from a recent
    vacation in Wengen, Switzerland - some of these were Ilford FP4+ and
    HP5+, a couple of Ilford SFX-200 (for the red sensitivity) and three
    rolls of Kodak TechPan rated at nominal 25ASA but exposed at a stop
    under and over in some shots. All 120-roll, of course.

    Now, I read, or have read, here and in other places, that TechPan is
    'tricky' or 'difficult' or 'you have to process critically' (etc etc),
    yet quite frankly the TechPan negatives I have are the best of the lot.
    Using Technidol developer at 20degsC for 10m 15secs with 10-secs
    agitation every 45secs dev time in a Paterson spiral tank, it has given
    me a great tonal range and of course fine grain and a very clear base.

    Now that is what I have come to expect - I've used TP120 for quite a
    time now, only of course when I need a faster film I opt for Ilford
    emulsions, even the Delta films. My quesion is: why do so many folks
    find TechPan so "difficult"?

    My next question is, clearly, what will come to replace TechPan after my
    'fridge stocks run out? Anyone any ideas?

    My regards, F.C. Trevor Gale.

    Because a little more sensitive to overexposure/over
    development than most other films.
    TMX-100. EI32 and develop in D-23.

  5. Development time for this combo? (The Massive Humungous Colossal Really Really
    Big Dev Chart only gives times for EI 100.)

  6. When Kodak announced the TechPan demise, it re-stirred some interest
    in the 20-30 35mm rolls I had in the freezer. I had drifted away from
    using it for many years as it seemed that if I was doing something
    that mattered for enlarging, I would be using medium format instead.
    I started tinkering with the old TPan rolls and it seemed that
    everything that I've tried (with reasonable adaptations to contrast
    control) has worked very nicely. I got especially nice negatives in
    W2D2+. I had only used the TP liquid back when I was first using it
    and haven't bothered to buy any in recent years so the film just sat,
    forgotten.

    Now, I'm finding that I'll miss having the option of using it in the
    future! Just playing around with non-important shots has shown me
    that it is very easy to work with.

  7. I use it for snapshots with a Leica RF. The smooth LF
    look is great for people shots.

    It is very well suited to any of the old ~f1.7 rangefinders
    from the age when Kodachrome 25 was popular; say a
    Cannonet or Olympus SP.

  9. I think partly because people try to develop it in
    standard developers relying on high dilution to get the
    extra-low contrast required. It may do that but will also
    distort the tone rendition.
    Kodak's recommended procedures work just fine.
    I used to use a lot of Tech Pan, developed in Technidol.
    I developed for slightly lower contrast than the Kodak
    guide, exposing at around EI-15 and
    using Technidol liquid.
    Since TP is now discontinued the closest to it is
    100T-Max in Microdol-X, but its not the same.

    I'm glad there's an alternative. What is D-23 developer? Is that
    Kodak product because I couldn't see it on their website or B&H etc. I
    it also a discontinued product?

    What does EI32 mean??

    What about Agfa or Ilford - do either carry a TechPan type product??

    Thanks - Sea

  11. It's a very simple home mix:

    Water at 125°F 750 ml
    Metol 7.5 g
    Sodium Sulfite 100 g
    Water to make 1000 ml

    There are many 2 bath versions, too.
    Exposure Index
    Can't recall what's happened to Agfa Copex but it seems to be
    available to some markets and is sold under other names (or was).
    Here's some info:

    http://www.8x11film.com/spur/engcopex01.html

    Ilford's PanF+ is very useful but is in a different category than TPan
    and other document films. TMax 100 is certain developers can give a
    super-fine grain effect. I don't use it but maybe someone else can
    direct you to some good TMax combos.
