If you want more than a point-and-shoot camera, the Canon Digital Rebel XTi/400D is for you. In automatic mode, you get the ease of having the camera determine the settings, but you can also choose the advanced exposure modes which give you more control over your camera settings. The following table shows you that you can adjust aperture (f-stop) to manipulate depth of field (the zone of sharp focus) and adjust shutter speed to determine whether moving objects appear sharply focused or blurry. In all five modes, you also can tweak color, ISO (light sensitivity), and exposure.
