Chapter 4. Understanding Exposure > Choosing an Exposure Method

Choosing an Exposure Method

You’ll find five Creative Zone methods for choosing the appropriate shutter speed and aperture: Automatic Depth-of-Field (A-DEP), Program (P), Shutter-priority (Tv), Aperture-priority (Av), and Manual (M). To select one of these modes, just spin the Mode Dial (located at the top-right side of the camera) to choose the method you want to use. You can also select from the Basic Zone exposure methods, which provide much less control.

Your choice of which exposure method is best for a given shooting situation will depend on things like your need for lots of (or less) depth-of-field, a desire to freeze action or allow motion blur, or how much noise you find acceptable in an image. Each of the Rebel T3i’s exposure methods emphasizes one of those aspects of image capture or another. This section introduces you to all of them.
