    simple theory: speed is to capture motion, f stop is for DOF. you play around with the 2 to get what you want your picture to look like.

    read your camera manual. it gives a good explanation of shutter speed and aperture value and how to use them.
    you can buy better gear but you can't buy a better eye

    i use the "sunny f16" rule.

    on a sunny day, shutter speed = reciprocal of the film speed you're using at an aperture of f16.

    e.g. if you've got iso 200 speed film (or in the case of your dslr, got the iso at 200) and a nice sunny day, you're shutter speed is 1/200 (or 1/250) and aperture f16.

    i use that as an anchor point, and work other exposures from there. remember, going to the next shutter speed, 1/500 or 1/100 is equivalent to decreasing or increasing by 1 f stop. similar rule applies with aperture, when you want to keep the shutter speed constant.
    Today is a gift; that's why it's called the present.

    to make the statement slightly more complete
