EXPOSURE MEASUREMENT

Getting the Right Exposure

The central part of the focusing screen should always

be aimed at the main subject when centering the

needle. Otherwise unimportant bright or dark areas

may give an exposure reading which is too high or

too low, resulting in under- or overexposure.

If an off-center composition is desired, first measure

the light striking the main subject

and

set the aperture

and shutter speed to center the needle. Then move

the camera until the desired composition appears in

the viewfinder.

For subjects of uniform tonal brightness, a reading

may be taken from any part of the subject. However,

if the subject is contrasty (sidelighted portraits, for

example), measure the light falling on the most impor-

tant part of the subject in which detail is desired in

the final picture.

For landscapes including large areas of sky, tilt the

camera downward during measurement or fill the

center of the finder with the main subject to prevent

underexposure of the main subject caused by the

bright skylight.

Photos:

1. Measuring the bright area in the center of the

screen

will

cause underex posure of the main subject.

2. For correct exposure, first measure the light

striking

the

main subject, then compose and shoot.
