Nikon N6006 - Manual (Page 159)

EV
Exposure Value. A number representing the available combi­
nations of shutter speed and aperture that give the same expo­
sure effect when the scene brightness and ISO remain the
same.
At ISO 100, the combination of a one-second shutter speed
and an aperture of f/1.4 is defined as EV1.
The camera’s meter may be used only within EV range of the
exposure meter. For example, with the N6006, exposure meter­
ing range is from EV0-EV19 at ISO 100 with f/1.4 lens.
Exposure compensation
Exposure compensation for available light is performed by
changing shutter speed and/or aperture via auto exposure
lock lever, exposure compensation button or auto exposure
bracketing.
In flash photography with a Nikon dedicated TTL Speedlight,
exposure compensation is also performed by varying the
amount of flash light output.
Exposure compensation made on camera affects both fore­
ground subject and background while varying flash output
amount affects only foreground.
Exposure control
Programmed auto: Camera controls both shutter speed and
aperture for correct exposure.
Shutter-priority auto: User selects shutter speed and camera
chooses aperture for correct exposure.
