Setting the Exposure for Shooting (A, B, C, DModes)

DShutter Speed and Aperture Value

The same exposure can be achieved with different combinations of shutter speed and aperture value, allowing you to freeze or blur motion and control depth of field. The following figure shows how shutter speed and aperture value affect exposure. When the ISO sensitivity setting (A74) is changed, the range of shutter speeds and aperture values at which the correct exposure can be obtained also changes.
