EXPOSURE MEASYMENT WITH THE PHOTOMIC FTn FINDER

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 influence the exposure reading.

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 im the viewfinder.

For subjects of unfform brightness, a reading may be taken from any part of the subject. However, ff the subject is

contrasty (sidelighted portraits, for example), measure the light faUing on the most important part of the subject in

which detail is desired in the final picture. For landscapes includimg large areas of sky, tilt the camera downward

during measurement or fiU the center of the finder with the main subject to prevent overexposure caused by the

bright skylight, otherwise the main subject will be underexposed.

Keep Out Stray Light!

The Photomic FTN Finder is designed to minimize the effect of light entering through the finder eyepiece

under normal picture-taking conditions. However, in the following situations the use of a finder eyocup is

recommended to insure complete exclusion of stray light.

• When the stop-down method of exposure measurement is used at small apertures

• When the camera is in suhlight and the subject is in shade

• When a shaft of sunlight falls between the eye and the eyepiece

When the needle on top of the finder is used to determine exposure, the eyepiece should be covered with the

hand to prevent extraneous light from entering the finderMeasuring the bright area in the center of the screen

will cause underexposure of the main subject.

For correct exposure, first measure the light striking the main subject, then compose and shoot.
