Color balance - Ektachrome film

    I just shot my first roll of 6x7 film (Ektachrome 200) and because it was of
    my daughter's wedding I wanted it back in a hurry, so I took it to a local
    place and they sent it out to their lab (got it back in two days). I'm sure
    that this lab isn't accustomed to doing 6 x7 film and the color balance was
    way off! I scanned the film and I was able to fix the color balance very
    easily in Photoshop by using the "Auto Color" adjustment, but my question
    is: isn't the film processing pretty straight forward for transparency
    film? I can understand how color balance could easily be off with negative
    film because of the need to add the correct filtration for printing the
    negatives, but with transparency film it should be a pretty straight-forward
    process, with no filtration variables involved. Any thoughts on this? I
    don't think I'll take my film there anymore :)

    I'm sure
    Maybe they did the same "correction" they would do on normal film ;)

  4. All Ektachrome and compatible E6 films are processed the same way. The
    only way the color balance can be off is if the photofinisher didn't use
    fresh chemicals or failed to keep to the specified processing
    temperature and time.
    Good labs run test strips through their machines frequently to ensure
    that everything is within spec. The fact that your film was 6x7 is not
    the factor.
    Probably the place the film was sent to does not get enough E6 to
    warrant good processing control. So, you are right, take your film
    elsewhere. Also, for the future, shoot a test roll before important
    pictures and make sure the camera, film and processing are correct.
    Another possibility is that you used outdated or improperly stored film.

  5. i'm curious - just how was the balance off? to blue? to red? what?

    E6 requires much more exactitude in both exposing and processing.
    As R.Feinman said you need to run clips,or a roll for your format, before
    you dip a whole production.
    So many things can go wrong: mechanical failure, bad emulsion, sloppy lab
    and even Champagne saturated photographers.

    As usual, the the photographer is the last person to taste the champagne,
    even if it's your own daughter; so a "champagne-saturated-photographer"
    wasn't the problem, DARN! :)
