    Yes, I agree with that. What I want to know is "How does one remove
    the white balance?". That white balance can be *removed* has been
    postulated, and I'm asking "How?".

    Floyd has skirted the subject with a voluminous "explanation" that
    states a default that can be changed, but conveniently skips over

    You have said "don't apply it" [sic] I assume what you mean is "Don't
    apply a *change*".

    Changing a default is not removing. It is simply re-setting. Not
    applying a new setting is not removing. It is simply allowing the
    default to remain in force. What's difficult to understand about

    I'm fully aware that the white balance can be changed. I do it all
    the time. I'm also fully aware that the image out-of-camera has the
    default setting.

    If not, you are so delusional that you think you have explained how
    white balance can be removed when you have not.

    I am not at all embarrassed that a non-answer is too much for me to
    take as an answer no matter how much that non-answer is buried in
    fustian camouflage.

    To use another analogy, you cannot conceal that you are out-on-a-limb
    by covering yourself with leaves.

    by not applying the transform.

    in aperture, you can click the little checkbox next to an adjustment
    and it will be applied or not applied. in this screen shot, only a
    level adjustment is done:

    camera raw doesn't expose that in the user interface but internally it
    can skip something if it doesn't need to recalculate it.
    if you want to nitpick (and i'm sure you do), yes, there's a default
    white balance that gets applied. it's a baseline that is going to
    happen no matter what adjustments you make.

    the point is that a raw converter can optimize what it needs to do. if
    all you do is change the sharpening, then there is no need to
    recalculate the white balance.

    So the "nitpick" has forced you out to admit that white balance is not
    No, the *point* is that the white balance is not removed.

    OK, now that you have finally come clean and agreed that the white
    balance is not removed, and the default white balance remains, let's
    see if we can get Floyd to talk sense.

    That stuff about the RAW converter optimizing is irrelative to the

    BTW..."recalculate" is another way of describing "change", not

    sometimes it is. if the white balance that has already been calculated
    is still valid then there's no need to recalculate it again, so it's
    removed from the list of transforms done and *not* done a second time.

    on the other hand, if you make an adjustment that does affect white
    balance, then what's cached is invalid and the white balance will need
    to be recalculated. in that case, it's not removed.
    good luck on that.
    it's *very* relevant. it does not do calculations it doesn't need to
    do, and skips them by removing them from the list.
    and when the recalculation is skipped, then that calculation is
    removed. very simple.

    Thank you for clarifying. Following your logic, if I make no change to
    the information contained in an image, since the information is not
    changed, it is removed and I get a blank image.
    I finally understand.

    So, in your mind, if something that has already been calculated, and
    does not need to be recalculated, then that means that it is

    I'd like to do that with my credit card statement. If I don't
    recalculate the balance, the balance is removed.

    Don't bullshit me with "removed from the list of transforms (that need
    to be) done (again)." That would mean that anything that needs not to
    be done a second time is removed.
    No, no, no. No more bullshit about "removing them from the list".
    "Removed" means "removed", not conditionally removed as in no longer
    on a list.
    Good Lord! You think "removed" means "not done" or "not necessary to
    do again".

    Removed = taken away, gone, now absent, not here anymore, etc.

    I am fascinated by this logic. It like watching a snake devour itself
    by eating its own tail.

    By your reckoning, if I open a RAW file and make no changes at all, I
    have removed white balance, tint, exposure, recovery, fill light,
    blacks, brightness, contrast, clarity, vibrance, and saturation.

    What do I have left?

    That skit was running through my mind. Also, the cheese shop skit
    where all of the cheeses had been removed.

    Come on, Alan. All that's understood.
    I challenge "removed". He's weaseling and now saying "removed from
    the list", but white balance is not removed.

    You came late to the thread and haven't seen the absurd claims.
    You've just seen the hasty cover-up.

    it doesn't work that way and that's not what i said.
    you clearly do not.

    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.

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