Exposure bracketing (D70)

Discussion in 'Digital SLR' started by Iceberg Concept, Inc., Aug 13, 2006.

  1. The D70 gives a range of exposure bracketing from -2EV to +2EV with numerous
    increments in between.

    Assuming that I want "one under, one over, and one right on" what determines
    whether I go in steps of 1/3, 1/2, or a full EV?

    Are there any guidelines for choosing?

    What do most people use?

    I would say the contrast range of the scene and what you are trying to
    achieve in the image eg if you can't capture the entire dynamic range
    you have to decide which bits you want to be correctly exposed and
    which bits not.

    The brightness and dynamic range of the scene.
    Yes. A 1/3 stop is a noticeable boost or cut in brightness level, but
    not a dramatic change.
    I don't really know since I still haven't talked to everyone...it's a
    lot of people you know.


    But I think the general consensus is that 1/3 is the common value used
    to bracket a typical shot.

    .... am I correct in my understanding that the f-stop & shutter speed are
    set, so exposure bracketing happens between the sensor and the saved
    file..therfore I have exactly the same result (and much more) if I shoot
    RAW and then adjust exposure comp on the RAW file...eg via Raw Shooter?
    - thanks -

    Not necessarily - bracketing will change the exposure of the shot if you pick
    exposure or flash bracketing, and you will need to take 2 or 3 pictures to
    complete the series.

    These 2 or 3 pictures will have different settings and different levels of dark
    and light and maybe burned white or black pixel areas.

    If you pick white balance, the camera takes only one picture but creates 2 or 3
    versions with different WB. This only works in JPG. RAW doesn't have WB.

    If you shoot RAW - don't worry about WB bracketing!

    I don't know. I can only tell you what I use. I almost never bother
    with bracketing by 1/3 of a stop, except possibly as a learning
    excercise. If I shoot RAW, I almost always will have that kind of
    leeway within one exposure, and also with JPEG:s, I normaly prefer an
    exposure compensation of -1/3, to be corrected if needed with "levels"
    in Photoshop, to fiddling with bracketing, if I'm afraid of blowing

    Thus, I never bracket for fine-tuning. I only bracket when I don't
    really have a clue. The smallest bracketing interval I would use is 2/3
    of a stop. That or a full stop is probably what I use the most.

    If I'm in a hurry and I can see the scene has a lot of highlights and
    shadows that might fool the auto-exposure I'll usually go + and - 0.7.
    Sometimes I just can't be bothered to try to get it right first time
    and I'd rather take loads and chuck the rubbish away later.

    Bracketing, in my opinion, is mostly called for in high contrast scenes
    (bright sun and shadows) and even -1,0,+1 isnt always enough. Lately I
    did a little testing of the useability of Photoshops HDR function and

    -1EV and -2, 0, +2 for bracketing was fine when the goal was a blending
    of 3 exposures. The result of my first test of HDR ever:
