P SA M Controlling Exposure: P, S, A, and M Modes

In (auto) and scene modes, the camera automati- cally adjusts shutter speed and aperture to produce op- timal exposure. In P, S, A, and M modes, shutter speed and aperture can be adjusted to suit the user’s creative intent. P, S, A, and M modes also give the user control over sensitivity (ISO equivalency; 52), white balance ( 54), manual focus ( 57), and the options in the shooting menu ( 85).
