EXPOSURE MEASUREMENT 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 in the viewfinder.
For subjects of uniform 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 important 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 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 eyecup is recommended to insure complete exclusion of
stray
light.
o
When the stop-down method of exposure measurement is used at small apertures
o
When the camera is in suhlight and the subject is in shade
o
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 finder
