EV As An Indicator of Camera Settings
EV corresponds simply to a combination of a shutter speed and an aperture setting, independent of any ISO setting—independent even of whether there is film in the camera or any light available.

Famous quotes containing the word camera:
“The camera relieves us of the burden of memory. It surveys us like God, and it surveys for us. Yet no other god has been so cynical, for the camera records in order to forget.”
—John Berger (b. 1926)
