Nikon N75 - Glossary

Glossary
CPU
Central Processing Unit. The electronic component
that controls an electronic product's functions .
AF Nikkor (including G- and O- type AF Nikkor) and
AI -P- Nikkor lenses have built -i n CPUs .
Depth of Field
See the column on page 102.
EV
Exposure Value : A number representing the
available combinations of shutter s peed s and
apertures that give the same exposure effect under
conditions of similar sce ne brightne ss and ISO .
At ISO 100 , the combination of a one -sec ond
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
N7S / N7SQO , the exposure metering range is from
EV1 to EV20 at ISO 100 with an f/1.4 lens .
Exposure
See the column on page 32.
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 N7SIN7SQO .
Automatic exposure bracketing is performed with
varied shutter speeds and/or apertures.
Exposure Compensation
In a situation s uch 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 -3 EV to +3 EV in
1 /2 steps is available with the N7SIN7SQO .
Flash shooting distance range
The distance range over which a flash can
effectively provide light. Flash shooting distance
range is controlled by the amount of flash output
available . Each automatic Speedlight's flash output
varies from maximum duration to minimum
duration. Close-up subjects will require lower (to
minimum) output, while more distant subjects will
require more light up to the maximum output.
The flash shooting distance range varies with the
aperture , film s peed , etc .
Flash synchronization ~
Timing of the flash so it coincides with release of _lliI
the camera's shutter. There are two types of
synchronization: Front-Curtain Sync, which fires the
flash at the start of the exposure , and Rear-Curtain
Sync , which fires the flash at the end of the 2
exposure.
Flash sync speed
Shutter speed at which the entire film frame is
exposed when the flash is fired in flash shooting.
The N7S / N7SQO's flash sync speed is 1/90 sec. or
slower.
