    I just received an order from fotoimpex.

    i thought i was ordering tri-x:

    http://www.fotoimpex.de/shop/de/ind... Rollfilme&artnr=3537&pn=0&sort=0&all=&items=

    but what arrived was "profilm professional film tri-x pan 400 black & white"

    from description:

    Kodak 400 ISO 400/27 TriX highly sensitive panchromatic B / W film with classic crystal and grain structure. Fine-grained with good resolution. Good sharpness and Grauwertübertragung, very high exposure latitude, very good drawing shadows. The classic for the art and reportage photography.

    Well..I don't mind trying something new, but WHAT IS IT?

    You got the right stuff. "Pan" is short for "panchromatic", which means that's it's sensitive to all visible colors, which is just what you want when you're taking a B&W picture of a colorful scene. It's just a name or a bit of marketing.

    From memory the original Tri-X wasn't full panchromatic. Pan just means Panchromatic which means the Black & white film has good sensitivity to all colours of the visible spectrum.

    Ortho chromatic films aren't sensitive to Red light, some films were between the two, EFKE 25 still is Verichrome was, Veirichrome Pan was fully Panchromatic.

    I assume that it is Tri-X 400, which is panchromatic, perhaps boxed differently for some market somewhere in the world. All common b/w films could technically be followed with "pan", though not too many are any more because it is assumed. If it is still there on product names, it is probably just for the sake of technicality, or because the product has been around forever and it was never taken off.

    For what it's worth, the Ps in HP and FP stand for panchromatic (you get the choice of either Highspeed Panchromatic or Finegrained Panchromatic), and let us not forget Pan-F.

    This is German "Gründlichkeit" !
    Tri-X was allway's a pan-film as long as I can remember (1975 or so).
    You will love this this film: honest grain, great impression of sharpness.

    Well, great, but it's not Kodak, so what is it? Tri-x knockoff? Something like an old tri-x? It's less expensive than Kodak's for sure!

    Hi:
    Pan X Pan= ASA 32
    Plus X Pan = ISO 125
    Double X Pan= ASA 250
    Tri X Pan = ISO 400 (320 Pro)
    Royal X Pan = ASA 1200

    In the way of the "X", an old time evplaned it to me (a very long time ago) is, Pan X = 1 stop, Plus X = 2 stops, XX = 2 1/2 stops, Tri X = 3 stops and Royal X Pan = 4 stops.

    Pan = Pancrhomatic film.

    The old film name included Pan. Kodak droped the Pan some time ago.

    As other posters have indicated, I'm sure it's the current Tri-X, perhaps a slight difference in labelling, maybe for different markets. Have a look at the local Kodak website for your country and Germany.

    And I'm sure it's genuine Kodak....their legal department would jump from a great height onto anyone infringing their trade marks with counterfeit goods. And Fotoimpex is an established and reputable firm.

    What makes you think its not Kodak? Is it in a Yellow box? I think Kodak and Tri-x are registered trademarks I doubt anyone else is making Tri-x.

    Tri x, Tri-x-pan, TX400 etc are all films made by Kodak and as far as I know the same thing.

    I would trust Fotoimpex.

    Well, it sure is labeled Kodak, is it not? And the description sure describes Tri-X. Interesting, though; is the fact that it is described as TriX professional, which I thought was always ASA (ISO?) 320, not 400.

    Back in ye oldene Dayz, Tri-X was marketed as a Type C Panchromatic emulsion whilst other Kodak films were considered Type B Panchromatic; each type having slightly different red sensitivity, IIRC (never a given.) Also, IIRC, there was a Tri-X Ortho in sheet films.

    I continued searching the fotoimpex site and found the statement that their 35mm "profilm" was bulk loaded from original manufactur-rolls. As it says "the film is the same; the cartridge is different.

    You purchased a 30 meter roll of bulk film, correct?

    That equates to my saying it wasn't originally fully panchromatic, I think the film changed in the early 60's. I'm just looking at a 1941 set of spectrographs for the Agfa (Ansco) films and the classifications/types of Panchromatic films that were then available. Back in the UK I have similar data for early Tri-X.

    Yes, indeed. And I remember, years ago, trying to find out if the Adox KB-14 (recently reintroduced, at the time, with production in Zagreb) which was listed as "orthopanchromatic" was a Type B or a Type C emulsion. For the life of me, I can't remember the answer!!:confused:
    I know we on APUG went through the "orthopancromatic" dance some time back.
    But I guess the simple answer (gosh, how we Apugers hate simple answers:tongue:) for OP is that what he bought is Eastman Kodak TriX.

    Does that mean that fotoimpex are loading the cartridges from bulk film themselves.

    Profilm bedeutet, dass wir die Filme aus original Meterware für Sie in preiswerte Patronen einspulen lassen. Der Film ist derselbe, die Patrone nicht.

    Sort of, RWman, that's what I understand from the above. But in fotoimpex's web site, they have two entries: Kodak and KODAK. If you choose the former, the search engine takes you to the bulk loaded "Profilm" and if you choose the KODAK (all capital letters) entry the search engine takes you to the great yellow father's yello/green boxes.

    There was at one time a Tri-x Pan Professional film especially designed for portraits with film speed ISO 320, available in roll and sheet but not in 35mm. This is NOT what they sent you. It is in fact Kodak Tri-X. Don't worry.

    Thats how I read it, with my limited German.
    I think I'd prefer to pay a bit extra for the Kodak-factory-packed and dated films. Though I've loaded my own cartidges from bulk in the past, with no probs.

    It is probably just like Freestyle who sells Tri-X under their own label "Premium Arista".

    Profilm means, that we have these films loaded for you into less expensive cartridges from bulk film. The film is the same, the cartridge is not.
