Metering systems and exposure are important factors for taking pictures. Knowing the characteristics of each factor helps you widen your photographic expression . • Metering Systems As the proper combination of shutter speed and aperture for correct exposure is determined according to subject brightness and film sensitivity, measuring subject brightness is very important. In general, brightness inside the viewfinder is not uniform. The N75/ N75QO provides two metering systems: Matrix Metering (page 26) and CenterWeighted Metering (page 60). With Matrix Metering, data on scene brightness is detected by the 25-segment Matrix sensor. Using G- or O-type Nikkor lenses, the N75/ N75QO camera performs 25-segment 3D Matrix Metering by adding distance information to determine correct exposure. With Center-Weighted Metering, brightness is detected at the central areas including five focus areas in the viewfinder. With the N75/N75QO, Matrix Metering is automatically selected when the exposure mode is set to other than Manual and Center-Weighted Metering is selected with Manual exposure mode. • Exposure Light from the subject passes through the lens and exposes the film. Light reaching the film is controlled by the shutter speed and aperture. The proper combination of shutter speed and aperture for subject brightness and film sensitivity results in the correct exposure. The N75/ N75QO's 'g' mode (page 26), Auto-Multi Program (page 54) and VariProgram (page 34) automatically control shutter speed and aperture. VariProgram gives you the option to choose from Portrait, Landscape, Close-Up, Sports or Night Portrait mode-designed for specific picture-taking situations and photographic images. In Shutter-Priority Auto exposure mode (page 56), you can manually set shutter speed and the camera automatically sets the proper aperture. In Aperture-Priority Auto exposure mode (page 58), you can manually set aperture and the camera automatically sets the proper shutter speed . In Manual exposure mode (page 60), you manually set both shutter speed and aperture. 32

Metering
systems
and
exposure
are
important
factors
for
taking pictures.
Knowing
the
characteristics
of
each
factor
helps you widen
your
photographic
expression .
• Metering Systems
As
the proper combination of shutter speed and aperture for correct exposure
is determined according
to
subject brightness and film sensitivity, measuring
subject brightness is very important.
In
general, brightness inside the viewfinder is not uniform. The N75/N75QO
provides two metering systems:
Matrix Metering
(page
26)
and
Center-
Weighted Metering
(page
60).
With
Matrix Metering,
data
on
scene
brightness is detected by the 25-segment Matrix sensor. Using G- or O-type
Nikkor lenses, the N75/N75QO camera performs
25-segment
3D
Matrix
Metering
by adding distance information to determine correct exposure. With
Center-Weighted Metering,
brightness is detected at the central areas
including five focus areas
in
the viewfinder. With the N75/N75QO,
Matrix
Metering
is automatically selected when the exposure mode is set to other
than Manual and
Center-Weighted Metering
is selected with Manual
exposure mode .
• Exposure
Light from the subject passes through the lens and exposes the film. Light
reaching the film is controlled by the shutter speed and aperture. The proper
combination of shutter speed and aperture for subject brightness and film
sensitivity results
in
the correct exposure.
The N75/N75QO's
'g'
mode (page
26),
Auto-Multi Program (page
54)
and Vari-
Program (page
34)
automatically control shutter speed and aperture. Vari-
Program gives you the option to choose from Portrait, Landscape, Close-Up,
Sports or Night Portrait
mode-designed
for specific picture-taking situations
and photographic images.
In
Shutter-Priority Auto exposure mode (page
56),
you can manually set shutter speed and the camera automatically sets the
proper aperture.
In
Aperture-Priority Auto exposure mode (page
58)
, you can
manually set aperture and the camera automatically sets the proper shutter
speed.
In
Manual exposure mode (page
60)
, you manually set both shutter
speed and aperture.
