    Re: Technical Pan Film

    Jiri,

    Would you care to share your times for Tech Pan and Rodinal 1:100? Agitation scheme?

    Does anyone have any experience with Tech Pan and Xtol, Diafine, Microphen? Jobo tanks and continuous agitation?

    Thanks.

    Wayne, why not?

    I develop my sheets in Jobo 2830 print drum (even if in this case it was a single sheet) rolled on UniColor Uniroller base - that is continuous agitation. Temperature was 19-21°C (I'm not that precise with temperature, it was most probably 20,...). Rodinal 1:100 for 8:00minutes.

    And the exposure was with my Minolta meter set at EI 25.

    Thanks Jiri!

    I have a similar Jobo set up for 120 and a Minolta meter as well.

    Jiri is correct. Expose at 25 ISO and Rodinal at 100 or 125:1 I continue to use it in 35mm & 4x5. I'm OK unless Seattle Light lets me down (its in the freezer). HC110 will work and the Formulary's specific developers work also. Yes it is great for high contrast situations.

    Re: Technical Pan Film

    I've used lots of stuff with TP, including c41 developer, TD3, very dilute Xtol, Pota, Technidol... Of those, I prefer TD3. That said, John Hicks (a reliable source) experimented extensively with this film, and he claimed that Ethol TEC produced by far the greatest real film speed. I don't know if it's still made, but if it is, then that's what I'd try.

    Re: Technical Pan Film

    old thread I know...

    I Love the tech pan, but I havn't tried it in 4x5 before this evening...

    I did as always: expose at 100 - dev in Neofin Doku for 6+ min, continous agitation..

    FANTASTIC to use on portraits!

    (difficult to scan: a lot of newton rings occured... I'll try again and upload some results.)

    Re: Technical Pan Film

    The way I heard it is that Kodak stopped actually making Tech Pan almost fifteen years ago. Everything sold since has been off that last master roll. They needed
    a specific polyester support material which was discontinued. Really pissed off the
    astrophotographers who prized this film for its extended red sensitivity. I still have quite a few sheets of 8x10 which I use for panchromatic highlight masking. There is no
    direct substitute, although there are other microfilms which can be soft developed for
    normal contrast range. The idea that Techpan would let a small camera shot look like a
    big camera shot was utter bunk all along. Yeah, it had extremely fine grain, if you could
    find a lens with adequate MTF to take full advantage of it. But the scale of the highlts
    and shadows was disappointing, and every little inevitable blemish in the sky or other
    smooth surface would enlarge to the size of the Goodyear blimp. I have a friend who
    used it extensively in medium format until I turned him onto Efke 25, and now is finally
    beginning to discover the detail that can be put into the extreme ends of the curve,
    something we LF practitioners have being able to accomplish for a long time with our
    silver-rich thick-emulsion films.

    I still have some TP in various formats. I develop mine in 510-Pyro 1:300, and get easy to print negatives.

    For general use, I too got the best results with TD-3.
