About Metering Systems and Exposure
About Metering Systems and Exposure
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 F75/F75D
provides two metering systems:
Matrix Metering
(page 26) and
Centre-
Weighted Metering
(page 60). With
Matrix Metering
, data on scene
brightness is detected by the 25-segment Matrix sensor. Using G- or D-type
Nikkor lenses, the F75/F75D camera performs
25-segment 3D Matrix
Metering
by adding distance information to determine correct exposure. With
Centre-Weighted Metering
, brightness is detected at the central areas
including five focus areas in the viewfinder. With the F75/F75D,
Matrix
Metering
is automatically selected when the exposure mode is set to other
than Manual and
Centre-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 F75/F75D’s
a
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.
