About Focus and Exposure

Focus, exposure and metering system are important factors for taking pictures.

Knowing the characteristics of each factor helps you widen your photographic

expression.

Focus and depth of field

When focusing, depth of field should be considered. Depth of field is the zone of

sharpest focus in front of and behind the subject on which the lens is focused. It

varies according to shooting distance, focal length and, above all, aperture.

Smaller apertures (larger f-numbers) will produce a deeper depth of field where

the background and foreground become sharper; larger apertures (smaller f-

numbers) will produce a shallower depth of field where the background becomes

blurred.

Cl Exposure

Light from the subject passes through the lens and is sensed by 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 N60/N60QD’s General-Purpose Program, Auto-Multi Program and Vari-

Program automatically control shutter speed and aperture. In Shutter-Priority

Auto exposure mode, you can manually set shutter speed and the camera

automatically sets the proper aperture. In Aperture-Priority Auto exposure mode,

you can manually set aperture and the camera automatically sets the proper

shutter speed. In Manual exposure mode, you manually set both shutter speed

and aperture.

Metering System

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 N60/N60QD

provides two metering systems: Matrix Metering and Center-Weighted Metering.

With Matrix Metering, data on scene brightness is detected by the six-segment

Matrix sensor. With Center-Weighted Metering, most of the meter’s sensitivity is

concentrated on the 12mm-diameter center circle in the viewfinder.

(With D-type AF Nikkor lenses, the N60/N60QD camera performs 3D Matrix

Metering. See page 48.)
