In certain cases, due to static electricity, the F75/F75D's microcomputer may turn the
camera off, even with fresh, properly installed batteries. For the same reason, the film
may not advance properly. In each of these cases, to resume operation, simply turn
the power off, then turn it on again. Or, remove and reinstall the batteries.

Glossary

CPU
Page
Central Processing Unit. The electronic component
that controls an electronic product's functions.
91, 97,
AF Nikkor (including G- and D-type AF Nikkor) and
98
AI-P-Nikkor lenses have built-in CPUs.
Depth of Field
See the column on page 102.
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
F75/F75D, 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 F75/F75D.
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 –3 EV to +3 EV in
1/2 steps is available with the F75/F75D.
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 speed, etc.
Flash synchronisation
Timing of the flash so it coincides with release of
the camera's shutter. There are two types of
synchronisation: 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
exposure.
Flash sync speed
Shutter speed at which the entire film frame is
exposed when the flash is fired in flash shooting.
The F75/F75D's flash sync speed is 1/90 sec. or
slower.
