Glossary CPU Central Processing Unit. The electronic component that controls an electronic product's functions. AF Nikkor (including G- and D-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 f11.4 is defined as EV1 . The camera can be used only within the EV range of the exposure meter. For example, with the N55, the exposure metering range is from EV1 to EV20 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 N55. 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 N55. 106

Glossary
CPU
Central Processing Unit. The electronic component that controls
an
electronic product's
functions.
AF Nikkor (including G- and D-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 I
SO
.
At ISO 100, the combination of a one-second shutter speed and
an
aperture of
f11.4
is
defined
as
EV1
.
The camera can be used only within the
EV
range of the exposure meter. For exampl
e,
with the N55, the exposure metering range is from
EV1
to
EV20
at I
SO
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 N55.
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 N55.
