CPU

Central Processing Unit. The electronic component that controls an electronic product'sfunctions.

AF Nikkor (including 0- and G-type AF Nikkor) and AI-P-Nikkor lenses have built-in CPUs.

EV

Exposure Value: A number representing the available combinations of shutter speeds and apertures that give the same exposure effect under conditions of similar scene brightness and ISO.

At ISO 100, the combination of a one-second shutter speed and an aperture of f/1.4 is defined as EV1.

The camera can be used only within the EV range of the exposure meter. For example, with the N65/ N65QD, the exposure metering range is from EV1 to EV20 for 3D Matrix Metering and Center-Weighted Metering, at ISO 100 with an f/1.4 lens.

Exposure bracketing

Shooting the same subject a number of times at a range of different exposures to attain proper exposure. Three shots with metered EV, under EV, and over EV exposure are performed in that order with the N65/ N65QD.

Automatic exposure bracketing is performed with varied shutter speeds and/or apertures.

Exposure Compensation

In a situation such as when your subject is strongly backlit, exposure compensation enables you to intentionally compensate the standard exposure value measured by the camera to create a desired effect. exposure compensation of ~2 EV to +2 EV in 1/2 steps is available with the N65/ N65QD.
