Read This If You Want To Take Great Photographs - Henry Carrol: Exposure

Shutter Speed controls the length of time that light enters your camera. Aperture controls how much light enters your camera. ISO controls how sensitive your camera is to light. The Good Shooting Modes are: P, S (Tv), and A (Av). The Bad Shooting Modes are: Scene Moods. The Ugly Shooting Modes are: Auto. When you're starting out, one of the best modes you will ever use is P (Program). If you are looking for total control of your shutter speed, use S or Tv (Shutter Priority). To Blur your moving subject, select Shutter Priority and a slow shutter speed. When shooting on slow shutter speeds, make sure your camera does not move. If it does, everything in your image will looked blurred. This is called "camera shake". To freeze movement, use "Shutter Priority" (S or Tv) and a fast shutter speed.  If you are looking for total control of your Aperture, use A or Av (Aperture Priority). To achieve a shallow depth of field select "Aperture Priority" and a wide open aperture (low f-number). Depth of field is at its most shallw when shooting close ups. A narrow aperture (high f-number) causes everything from the foreground through to the background to be in focus. Always set your ISO first, as it affects what shutter speed and aperture you can use. Increasing your ISO is essential if you want to use fast shutter speeds in low light. When you're trying to get familiar with all the technical stuff, using "Manual" slows you down, adds confusion, and worst of all, means you risk missing the shot. Meet the alternative to Manual, Exposure Compensation. To draw out details in the shadow, use Exposure Compensation and scroll towards the +. To silhouette your backlit subject use Exposure Compensation and scroll towards the -.
