Shutter 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.
