Metering systems and exposure are important factors for taking pictures.
Knowing the characteristics of each factor helps you widen your
photographic expression.

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 F100 provides
three metering systems: Matrix Metering, Center-Weighted Metering and Spot
Metering. With Matrix Metering, scene brightness data is detected by the 10-
segment Matrix sensor. With Center-Weighted Metering, most of the meter’s
sensitivity is concentrated on the 12mm-diameter center circle in the viewfinder.
Spot Metering sensitivity is concentrated in a small, selected focus area from
five available focus areas. Using D- or G-type Nikkor lenses, the F100 camera
performs 3D Matrix Metering by adding distance information to determine
correct exposure. See page 44.

Light from the subject passes through the lens and exposes the film. Shutter
speed and aperture control how much light reaches the film. The combination of
shutter speed and aperture appropriate for subject brightness and film
sensitivity results in correct exposure—a result provided by the F100’s four
exposure modes: Programmed Auto (page 46), Shutter-Priority Auto (page 48),
Aperture-Priority Auto (page 50) and Manual (page 52) exposure modes. Also,
the F100 offers auto exposure lock (page 54), exposure compensation (page 56)
or Auto Exposure/Flash Exposure Bracketing function (page 57) allowing a
photographer greater control of exposure than that afforded by Auto exposure
modes.
