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 F65/F65D
provides two metering systems: Matrix Metering (page 28) and Centre-
Weighted Metering (page 58). With Matrix Metering, data on scene
brightness is detected by the six-segment Matrix sensor. With Centre-
Weighted Metering, most of the meter’s sensitivity is concentrated on
the 12mm-diameter centre circle in the viewfinder. With the F65/F65D,
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.
Using D- or G-type Nikkor lenses, the F65/F65D camera performs 3D
Matrix Metering by adding distance information to determine correct
exposure.
•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 F65/F65D’s AUTO mode (page 51), Auto-Multi Program (page 52) and
Vari-Program (page 36) automatically control shutter speed and aperture.
In Shutter-Priority Auto exposure mode (page 54), you can manually set
shutter speed and the camera automatically sets the proper aperture. In
Aperture-Priority Auto exposure mode (page 56), you can manually set
aperture and the camera automatically sets the proper shutter speed. In
Manual exposure mode (page 58), you manually set both shutter speed
and aperture.
