    Digging through an old box of goodies I received from a friend, I just found an old sealed bulk 35mm film container labeled "Kodak Technical Pan Film 2415" and there is a serial number that is partially written over. Someone has written Unex. Test Roll "Short" in marker on the container.

    I've rolled a couple short rolls of this to test it, but I was wondering if anyone could tell me what speed tech pan is? Assuming it is tech pan I guess! While loading it I noticed that it is a pretty dark looking film, very dark gray. Much different than the Tmax that I had in the loader before this. Thanks.

    One more question. Has anyone out there tried developing this film with XTOL? Just curious. Thanks.

    Good Evening, David,

    Tech Pan can be exposed at various indices, depending on the subject matter and the developer used. For general pictorial purposes, an E. I. of approximately 25 is generally used, assuming that the developer will be Technidol (or similar).

    if you shoot it at a high asa ( 200 i think?) you will get a high contrast negative. you can process the film in paper developer like dektol &C.
    the negatives, even when shot high contrast, are grainless.

    not sure if it is true or not, but i have heard that techpan goes bad soon after expiration. :sad:

    good luck!

    ps. i've posted an image ( high contrast ) in my personal gallery ...

    You know, I used TP back in the eary '80s. Still have about 100 feet left in the bulk loader. Tried a roll last week, developed in HC110 dilution "F". Fantastic results. very smooth, no grain. Who says film expires??

    It's the technidol developer that doesn't last long after being mixed.

    As a matter of fact, what brought me back to TP was that I found a 36 exposure roll (undeveloped) in my darkroom. There since the '80s. Loaded it into my Jobo and developed (after 20 something years, the Latent image held up just fine, amazing!!
