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.
