Exposure Compensation On Still Cameras
In photography, some cameras include exposure compensation as a feature to allow the user to adjust the automatically calculated exposure. Compensation can be either positive (additional exposure) or negative (reduced exposure), and is frequently available in third- or half-step, less commonly in full steps or even quarter-step increments, usually up to two or three steps in either direction; a few film and some digital cameras allow a greater range of up to four, five or even six steps in both directions. Camera exposure compensation is commonly stated in terms of EV units; 1 EV is equal to one exposure step (or stop), corresponding to a doubling of exposure.
Exposure can be adjusted by changing either the lens f-number or the exposure time; which one is changed usually depends on the camera's exposure mode. If the mode is aperture priority, exposure compensation changes the exposure time; if the mode is shutter priority, the f-number is changed. If a flash is being used, some cameras will adjust it as well.

Famous quotes containing the words compensation and/or cameras:
“The only compensation which war offers for its manifold mischiefs, is in the great personal qualities to which it gives scope and occasion.”
—Ralph Waldo Emerson (1803–1882)
“While the music is performed, the cameras linger savagely over the faces of the audience. What a bottomless chasm of vacuity they reveal! Those who flock round the Beatles, who scream themselves into hysteria, whose vacant faces flicker over the TV screen, are the least fortunate of their generation, the dull, the idle, the failures . . .”
—Paul Johnson (b. 1928)
