    not what i said.
    an incredible lack of understanding, something i doubt will ever change.

    there's no weaseling nor is there any change in what i'm saying. you
    don't understand how it works.
    there's no cover-up either, only your lack of understanding. you're in
    well over your head.

    yes, when the file is reopened, everything needs to be redone, but
    that's not the issue.

    floyd said everything needs to be redone with even the slightest change
    in *any* adjustment, while the file is open. that's false. it depends
    what was changed.

    If that's understood then you're wasting your time and everyone's
    bandwidth by carrying the discussion any further.
    Who gives a shit about nospam once again in trying to wriggle out of his
    own straight jacket. Really.

    For someone with such a small shovel you can sure dig deep holes for
    yourself.

    Floyd digs even deeper holes than you, with a smaller shovel and quicker
    to boot.

    How can you know?

    The editing functions will be working on the in-computer image formed
    by the convertor from the raw data. Unless you are claiming that you
    know differently as a result of you having decompiled ACR and
    understanding what you have got. :)

    The D300 determines white balance on site. Even though it doesn't
    apply it to the raw data, it's there in the file and most (all?) raw
    convertors with which I'm familiar use that as their initial setting.
    I find I almost never have to choose another value.

    I wondered when someone would get sensible. White balance is not
    something you can remove. Without white balance data you can get
    absolutely no meaningful image from raw image data.

    A raw image file is a collection of numbers. These numbers have to be
    converted into a different set of numbers which let themselves be
    interpreted as colours. These form some kind of in-computer image file
    which lends itself to being seen on the screen as an image.

    The raw data cannot be converted to the in-computer image file without
    information about what the raw data actually means. Colour is a large
    part of this and white balance is an important part of the colour
    information. Without white balance data the in-computer image cannot
    be be converted to a visible image file. Remove white balance and you
    have no image.

    Adjusting white balance settings means thnat every single one of the
    image pixels have to be recalculated. Some may not be changed but that
    can only be determined by evaluating it. But it's not possible to
    change just some of the image. The white balance change has to be
    applied to every single pixel. To suggest otherwise makes no sense.
    Which hopefully will affect the temperature of everything in the room.

    So you snip all relevant material, including detail.
    I simply followed what you said to its logical conclusion.

    because that's all it has to work with.

  13. Easy answer: just let the time run backwards to the point
    where the photons hit the sensor.
