When working with digital, you generally have less dynamic range to work with, so you have to nail your exposure in camera. The preview on the camera's lcd is often deceiving. Setup your camera to show the histogram when you shoot, so you can see exactly how you're exposing. I like to have the highlight alert on (can't remember if that's what it's called right now), so it flashes areas of the photo that are clipped.
