CPU
Central Processing Unit. The electronic component that controls an electronic
product's functions.
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 meteri
ng 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 bracketi
ng 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.
