    I used to shoot alot of high key photography (white on white) in my studio
    when I shot in the film world but since the change over to my Canon EOS 1
    Mark II digital camera when I try to light up the white background it blows
    it way off of the scale, to hot?? Anyone suggestions, besides stay away from
    shooting high key? Thank you in advance..

  2. since the change over to my Canon EOS 1 Mark II digital camera
    Maybe I'm missing something obvious, but why is there a problem? Yes,
    digital in general will blow highlights easily with poor metering, but
    a 1dsII will *more* than make up for that in the shadows, so you just
    need to experiment and either bring your exposure back, or wind down
    the lighting. Maybe you will have to adjust the balance between your
    backlights and main, but overall, it should just be a very minor
    adjustment to your technique to get your brightest highlights to be
    just at the clipping level.. Then a bit of tweaking in
    post-processing, and Bob's your aunty..

    Get those flash/light meters out and start from scratch, think like you
    are shooting slide film if it helps..... (O:

    If you want more specific advice, what film were your shooting? What
    sort of lights are you using? Post examples/histograms..?

  3. Using a plain white wall or seamless paper, the background should be 2
    stops brighter than the subject.

  4. What you said can't be what you were thinking, right? Wanna rewrite that?

    Now who's being nasty? ;-)

    That out of the way, my suggestion with digital is to have the
    background 1 stop (not the traditional 2 stops) brighter than the subject.
    It stops the fine details on the edge/outline of the subject from
    burning out.

    Try both (1 and 2 stops) and see for yourself, it's only a few seconds
    more and few more bits on the flashcard.

  6. 2 stops. Anything more blows it out, anything less and you get gray.
    Now, that's assuming that you're lighting the background separately
    from the subject, which is what you should be doing.

  7. That is assuming your "subject" is close to 18% grey and is what
    was metered.
    How about if the background is illuminated at just under
    whatever maximum the camera can record at the chosen exposure
    settings, while the subject is illuminated to provide whatever
    is *appropriate* for the image desired. If the subject is
    nearly black, it certainly should be more than 2 stops
    difference... and if the subject is white is certainly shouldn't
    be any 2 stops...

    Using a 2 stop rule of thumb and then metering incorrectly
    (which results in improper exposure adjustment) is exactly what
    the OP was doing to get blown out highlights.

    You have to treat digital capture more like shooting chromes than
    negs. Digital sensors are rather tolerant of underexposure, but clip
    on overexposure, rather like blowing the highlights on slide film.
