    Speaking of old film, years ago after shooting rolls of slide film, Fuji
    Sensia brand I think, 100 and 400 speed, I tossed the rolls into the freezer
    hoping to preserve the latent image until I had enough rolls saved to mix up
    the chemistry and process. 1 month later, the ISO 100 film came out perfect
    while the 400 speed came out with a blue cast. It was as if I had left a
    tungsten light correcting filter over the lens but perhaps not as strong.

    Freezing film should slow its degradation to nearly a stop as refrigerated
    (40 Deg F) professional films are held near their peak for months.
    Apparently the latent image will degrade even while the film is chilled to 0
    Deg. F.

    I guess my question is, what color shifts are to be expected with a degraded
    latent image on this brand of slide film? It could have been a processing
    error on my part, but I never made an error in 80+ rolls (except for the
    very first time when I processed Kodachrome in E6 chemistry!).

  2. One month, with or without freezing should not have caused any
    measurable shift. It would appear there was something else at play. Maybe
    the 400 speed film had been somehow damaged before you even got it?
    Freezing should have reduced the effect, not increased it.

    I don't think you can talk about expected color shifts by brand, rather
    by emulsion type and that sometimes changes without public notice.

    Even with a latent image? I always heard never let exposed slide film sit
    for more than a couple weeks without processing.

  4. Yes.

    Nope. I've tossed my Provia 400F into the fridge for a month or more
    before sending it off to the lab. The slides came out just fine. OTOH
    a roll of Kodak elite chrome 400 I had the misfortune of trying, looked
    really weird after sitting in the fridge for 3 weeks after shooting.
    The colors were all yellowish.

    Since you can't fix them up with Photoshop, you might try viewing them
    through a blue filter.....This might work for slides taken indoors under
    incandescent lights with daylight type film, too. One could even glue a step
    up/down filter ring to the projector lens......

    Well there were times when I've had exposed slide film of various brands
    sitting in the fridge for up to 8 months that when processed turned out
