    What are the best settings to use for Canon 30D with Sigma 18-200mm
    f/3.5-6.3 lens for baseball on bright day. I'm having problems and
    most of my photos are too dark.

    TIA

    What metering are you using? For me, evaluative seems to work best in the
    situation you mention.

    For some past pictures, it was set to patterned. I use aperature
    priority so that I can let in the most amount of light. I'm using
    ISO-800 to capture the baseball in mid air and the swing of the bat.
    I'm just not getting all of the necessary settings right. Any helpful
    hints would be appreciated.

    The amount of light that reaches the sensor is based on two things,
    not just one. Aperature priority means the camera changes the shutter
    speed to limit how much light hits the sensor. As you open the
    aperature the camera will pick a faster shutter speed, as you close
    the aperture the camera will pick a slower shutter speed. If you
    change to TV and set the shutter speed, the faster the shutter the
    wider the camera will set the aperture and the slower the shutter you
    set the smaller the camera will set the aperature. In all 4 cases the
    same "amount of light" will be allowed to hit the sensor. That's how
    auto exposure works.

    To "let in the most amount of light" you need to either change the
    exposure value compensation (EV) or use manual settings that let in
    more light than the camera lets in when you use auto exposure.

    I personally would use TV rather than AV because you need a minimum
    shutter speed to get crips shots of sports action.

    The type of lens and camera you are using are relatively unimportant
    for this situation (bright daytime light).
    If the shots are too dark then set the EV up a partial or full stop.
    Look in your 30D manual for the exact way to change EV in that camera.

    And please don't top post. See what a mess it makes of the threading?

    p.s. normally I'd delete the text below, but I'm leaving it in to show
    how confusing top posting is.

    If you are trying to capture action then shutter priority so you can choose
    faster shutter speeds would work better for you for things like stopping
    balls in mid-flight. At ISO 800 in daylight even the smallish maximum
    aperture of the Sigma at 200mm should still allow fast shutter speeds. For
    its price this lens performs quite well at medium and long focal lengths.
    Too bad Sigma never actually released the image stabilized version of this
    lens that they announced last September.
    I presume you are using jpeg as with raw some slight apparent underexposure
    would actually be helpful in trying to end up with an image that has the
    appearance of expanded latitude. But then you would have to spend the time
    processing each image, just like you would if you did your own darkroom work
    with film processes. The best results require a little thought and a little
    work.
    Since jpeg emphasizes the worst aspect of digital sensors, limited latitude,
    you have to make some choices about what parts of your image you want to
    emphasize within the apparent correct exposure range and this requires
    experimentation, for example adjusting EV settings, to gain the experience
    of what works for you. There are no perfect formulas, only guidelines.
