after adjustment, picture blur may result—use a
tripod, higher speed film or electronic flash.
• Picture blur—Rotate to a smaller f/number. If the
shutter speed does not increase above 1/30 sec.,
use a tripod to steady the camera, change to a
higher s.oeed film or use an electronic flash.
Note: If the audio warning system is not turned on. check the
LEDs in the viewfinder lor im proper exposure conditions
before shooting.

epth of field
epth of field refers to the clear focus zones in front
and behind the main subject when you focus the
ns. With the FG’s aperture-priority automatic expo-
ire, you have full control over depth of field by vary-
g the f/stop. The following are important points to
member.
) By stopping down the aperture to smaller openings
(larger f/numbers), depth of field becomes deeper
and not only your main subject but foreground and
background will also be in clear focus. On the
contrary, by opening up the aperture to larger
openings (smaller f/numbers), depth of field be­
comes shallower and both fore- and background
will be out of focus, thus enabling you to empha­
size the main subject.
(2) The farther the subject from the camera, the
deeper the depth of field; the closer to the camera,
the shallower the depth of field.
(3) Usually, background clarity is sharper than that of
the foreground; thus, in shallow depth-of-field
situations, you can expect your foreground images
to be less clear than those behind the subject.
(4) The shorter the focal length of ihe lens, the deeper
the depth of field.
(5) With Nikkor or Nikon Series E lenses, depth of field
is indicated by pairs of colored lines on the lens
which correspond to the colors of the f/number.
Therefore, depth-of-field range can be obtained by
the corresponding distance scale.
