is this kind of bracketing possible?

    Suppose I know exact the exposure value that I want. I could determine
    the shutter and aperture value and obtain the perfect picture...

    but i am not sure I get the depth of field I want. DOF preview is
    useful, but it's better to look at the final print. or perhaps you are
    in a hurry and don't have time to fool with DOF. Is there a camera that
    would take several shots (3 or 5), with different Tv and Av so the
    exposure is the same, but you get different DOF???

    And only for digital guys, is there a camera that would take a picture
    withe different white ballance settings? ( I know you can tweak this
    later on computer, either from RAW files, or in photoshop), but still,
    for mam and pop without computer knowledge it might be useful.

    BTW: dear not so SexySusan, I don't need your opinions, and welcome to
    my killfile

  2. Most or all of the digital SLRs will do all of those things. Custom white
    balance settings is the norm for those devices. As to your first question,
    Nikon and Fuji call that "flexible program" mode. You can point the camera
    while in Program mode and it will determine the optimum EV according to it's
    program. You then have the option of turning a dial which simultaneously
    changes the aperture in one direction while changing the shutter speed the
    same number of stops in the opposite direction, thus maintaining constant
    EV.

    Those cameras mostly all have DOF preview buttons too.

  3. Canon has the same feature on both their film and digital SLRs, called
    "program shift."
    It isn't automatic, like automatic bracketing, but it is easy.
    As far as white balance, I just did that with my D30, shot images with two
    different WB settings to get the right one. I think that is a pretty common
    feature, too, with DSLRs, as is "custom" white balance.

    Set on aperture priority and take several shots at differing apertures?

    Just put the camera into aperture priority mode. Set the aperture where you
    think the dof will be what you want and shoot. Then reset for more or less
    dof and shoot again, etc. Any camera with aperture priority will do this
    and, you can do it with shutter priority too. Every time you change the
    shutter speed the camera will set a new aperture to compensate and all the
    shots will have the same exposure.

  6. I'm assuming you mean 'auto' bracketing here ... the camera taking its 3/5
    shots with one press of the shuttter release...
    With Canon SLR's auto exposure bracketing in Tv mode will change the
    aperture ... varying DOF results.
    There is white balance auto bracketing on the Canon DSLR's ... The 10D has
    this feature adjustable +/- for three shots up to 15 (5/10/15) Mireds.

    but this also changes the *exposure*. I wonder if there is a camera that
    changes both so the exposure stays constant.

  8. This is true ... With many images when using colour print film this will not
    really matter - but that's a bit limiting to say the least. As others have
    suggested it's just a case of shifting the exposure settings yourself - Does
    anyone actually use these 'auto' bracketing functions anyway?

    Many (ie. not the budget models) Pentax bodies do the same. With the body
    in programme you just turn one dial to move up or down the programme line -
    keeping the same exposure but changing the shutter speed in one direction
    and the aperture in the other.

    Something along these lines is fairly common on the 'better' bodies from
    most manufacturers.

    Just like someone else already mentioned...set the camera to APERTURE
    PRIORITY, then shoot several shots, changing the aperture as you go
    along. The shutter speed will automatically be adjusted to make the
    same exposure as the one you used at your starting point.

    In message <>,
    You'll get three pictures with three different depths of field, but one
    will be grossly under-exosed, and one grossly over-exposed.
