Editing Exposure value (section)

==EV as an indicator of camera settings==

Used as an indicator of camera settings, EV corresponds to actual combinations of shutter speed and aperture setting. When the actual EV matches that recommended by the light level and the ISO speed, these settings should result in the "correct" exposure.
