    I got my new Rebel XTi for Christmas. I am trying all settings and getting
    to know it. I have to admit I am also a novice. MY question is this...when
    I take pictures on FULL AUTO in normal inside light the ISO is set at
    ISO400. Is this normal or have I somehow accidentally changed the default
    setting? Thanks for the time.

    I don't have that model, but usually there is a menu option to reset
    camera to factory defaults (this will also reset the internal file
    number stored in the camera).

    I don't have an XTi manual, but if Canon's manual for their G7 is
    any indication, ISO 400 would not be out of line. It states:
    Now ISO 400 might result in problematic noise being introduced
    with most P&S cameras, the XTi should have very low levels of noise
    at ISO 400, resulting in good, clear pictures that can still be used
    to make very large prints. If your FULL AUTO setting still results
    in ISO 400 when pictures are taken in brighter settings, such as in
    outdoor daylight, *then* something may be wrong, as I'd think that
    the camera should have used a lower ISO. From the way you phrased
    your question I'd guess that your XTi's FULL AUTO setting is similar
    to the G7's ISO AUTO setting and that it's operating properly.

    The G7's manual indicates in a table on page 39 that the available
    ISO speeds on the G7's dedicated ISO speed dial include ISO AUTO,
    ISO HIGH, and ISOs 80 through 1600. When the camera's shooting mode
    is set to AUTO (instead of P, Tv, Av, M, etc), it honors the dial
    selected ISO speed only if it is set to either ISO AUTO or ISO HIGH.
    For all of the other ISO settings (80 - 1600), the G7, when in AUTO
    shooting mode reverts to ISO AUTO. Check your XTi's manual. I
    assume it will have a similar table showing the ISO speeds used for
    the various combinations of shooting mode vs. selected ISO speed.

    This is the problem with using Full Auto.
    It selects your speed, F stop and ISO. Most often, if the light is low the
    camera will select a higher ISO. In your case, the XTI well supports the 400
    ISO without too much noise. However, you would be better off to select "P"
    (Program) and select yourself the ISO (preferably 100 or 200) and WB (white
    balance). You would certainly get better results. Of course, if the light
    were not strong enough, you could then select a higher ISO, but you're the
    master of the situation.

    From the XTi manual,p.53 "In the Basic Zone modes, the ISO speed will
    be set automatically within ISO 100-400 to match the respective light
    Full Auto is a Basic Zone mode.

    Realizing this is an older thread, perhaps someone can help me...

    I have the XTi and have been trying to take a time lapse of the night sky. I can not get this POS camera to take any kind of picture in under light situations. Is there a feature that prevents users from doing this?
    I have tried (P) and I have tried (M)... nothing. As soon as I am in a dark situation, I can't take any shots.
    Thanks in advance.
