    So, do you know, did all of the emulsions that Kodak made up until the "big kill off" (when they axed "Verichrome", "Ektapan", "Commercial") -- which seemed to coincide with the cut over to the "new coating plant" -- get 'made over' to the Modern methods or were these still Recent recipes at the time they were discontinued?

    I'm presuming that PX and TX got "Modernized" at some point, due to their relative popularity.

It's a generous medium, photography." -- Lee Friedlander

    Kirk,
    I don't think that we can wait for your daughter to get married . Can't you just put her up for adoption and get to work? I mean, Dude, get your priorities straight!

    I work with a lot of outdated films. Both Konica color films and Shanghai GP3 black and white deteriorate in really remarkable ways. I never see anything like this with Kodak, Fuji, or Ilford (or former east-bloc films). What you are saying in this post about the importance of finishing, and how complicated it is, has me convinced that their problems relate to a poor understanding of stabilization. Except for stability, I find both films otherwise quite good.

    David, you are exactly correct.

    Thanks for a good post putting the problem clearly before us.

    I just have to stick my head in here too... does the liquid emulsions (such as Foma) undergo the same complex finishing touches? Or are those emulsions, primarily meant to be paper emulsions, less complex?

    Actually, paper emulsions can be just as complex as film emulsions when undergoing finishing. The reason is the exacting control of curve shape and fog, and also for keeping.

    The liquid emulsions do caution you to be careful as after each heating they may change. This is a sign of "old style" finishes using just sulfur or sulfur + gold.

    However, many paper emulsions were never finished at all. They were made in such a way that they gave the right characteristics right out of the "pot".
