    Hi-

    I'm curious if people have had experiences with this new film and what
    they were. The only way I found out there even *was* a new emulsion
    was from digitaltruth.com...None of the local photo joints seem to
    carry it so I'm wondering what i'm in for when I order it online.

    Thanks!

    Hey Dude. Me thinks you ought to go straight to digital. If you don't have
    any more sense than to ask questions about a film you don't even identify,
    you don't DESERVE to participate in using up the diminishing quantity of
    film left. So, go to digital where you won't leave any trace [and won't use
    this newsgroup either].

    Merry Christmas.

    He does identify it. Agfapan APX 100 & 400. Read the subject.

    The 400 is "new and improved" I didn't think the 100 was changed. I don't
    use the 400 so can't comment. If the local place is selling fresh 400 it's
    the new and improved stuff. If you go to the Agfa website it likely mentions
    the batch number the new stuff started with. Finding the info might be a
    challenge.

    The "new" APX 400 is in the same type of box as APX 100 has been in for
    a little time now. Agfa have extended the times for development
    somewhat. Because I've always got a slightly longer developing times
    with the 400 film over the 100 film (as is usual for 400 speed films
    over 100 speed films but contrary to the former Agfa information), I
    think, at least, this is partially goes some ways to rectify that
    anomoly. Remember Agfa recommended one minute less for the development
    of APX 400 than APX 100 in Rodinal 1+25...

  8. The Digital Truth site says the _base_ was changed and new
    times were published. The combined film data booklet on the
    Agfa site is dated 2003 and indicates that APX 400 is "new
    generation" but nothing about APX 100.
    Changing the base should not have an effect on development
    time or other emulsion characteristics. I am puzzled by what
    exactly Agfa changed, there isn't a clue on their web site,
    at least not that I could find. The time for some Kodak
    films changed because they changed the overcoating of the
    film. Overcoating is used to protect the emulsion from
    abrasion. Its usually a thin coating of hard gelatin. The
    developer must penetrate this layer to get to the emulsion
    so its swelling time and thickness affect developing times,
    especially relatively short times. The support, OTOH, is
    just there and has no effect.
    Its possible that Digital Truth misinterpreted something
    that Agfa published. Without the original Agfa announcements
    its impossible to tell.
    I can believe Agfa may have revised their development
    times because some of them were clearly off and some were
    different in different places, such as on developer
    instruction sheets and on film instruction sheets. One cause
    of this was that they were not for the same contrast index.
    Agfa seems to have fixed this which is good. They are only
    about ten years late doing it.
    If anyone knows where to find the actual Agfa announcement
    I would be glad to know.
    To answe the question directly, evidently there is no
    difference in Agfapah 100 and probably none in the emulsion
    of Agfapan 400.
    Agfa makes some excellent films and other products. Their
    papers have been long my favorites, but they are just dumb
    as the dickens (or maybe its chickens) when it comes to
    marketing.

  9. I am seeing the word "professional" splashed across the APX100 box now... I
    buy film in blocks so there is considerable time between my actually
    'looking' at things, but I don't remember seeing that before...
    Semanttics or ??

    Seems ala Kodak and TXP 320 / TX 400...

    I have no idea what this means. Kodak used "professional"
    on films which had retouching surfaces on them. It uses the
    term for color films which are intended for immediate use
    and are shipped and stored refrigerated. Their amateur color
    films are made to drift through the optimum color balance
    slowly over time, pro films are optimum right now. But by
    doing that the shelf life is limited.
    My favorite current meaningless term is "prosumer". Maybe
    it means the push buttons are bigger.

    Hi, I saw an official announcement of the new developing times of the
    new version of APX 400 and it stated that the new film has a new base,
    as Richard pointed out, and that the developing times have changed -
    that's it.
    In a photo.net thread a little while ago someone showed that the
    developing curves were indeed different from the old film to the new
    film (not their own curves, the manufacturers ones)... I'm not convinced
    these so called "new" curves bare any meaning in this case as I've been
    getting very similar results to what I used to get with the old APX 400.
    However, it is difficult for me to check this properly, as I use a
    slightly different film developer than I used to... So, for me Richard's
    explanation seems realistic, a new base, which doesn't change the
    developing time, and a new set of times to get APX 400 more in line with
    the times for APX 100.

    Begging your pardon, sir; "prosumer" means that the push buttons are not
    labeled as to their function!

    That's pretty obnoxious. Didn't your mama teach you any social graces at
    all. If you don't have anything positive to contribute keep your mouth shut.
