Correct
exposure-whether
your photo comes out
just right and neither too dark (underexposed) nor too
light
(overexposed)-depends
on
two factors
in
re-
lation to your film: light and time. These factors are
controlled by f/stop (aperture opening) and shutter
speed.
The
FG
offers three different ways (modes) to
expose
photos-P
(Program), A (Auto) and manual.
Depending
on
photographic conditions and your own
personal requirements, choose
anyone
of these
three.
On
P,
exposure measurements are totally
handled
by
the camera,
so
all
you do to take perfect
pictures
is
focus and shoot.
On
A,
still enabling auto-
matic exposure, f/stop
selection
is
under your con-
trol, allowing you to create special depth-of-field
effects, and the
FG
matches with the correct shutter
speed. (For
details
on
depth of field, refer to page 32.)
On
manual, both f/stop and shutter speed selection
are controlled
by
you, giving you the chance to
achieve
special effects and to grow
in
your photo-
graphic
skills.

P-programmed
exposure
mode
A new feature with the Nikon
FG,
the P mode not only
greatly simplifies
operation, but also lets you con-
centrate
completely
on
picture composition and
further, gives you greater opportunities to shoot,
especially
in
quickly changing situations or for candid
shots, because no exposure
calculation
is
necessary.
On
P,
the optimum combination of step less shutter
speed and step
less f/stop
is
determined by the FG's
microcomputer at the instant of exposure, according
to a
scientifically pre-arranged program. Perfect
exposure
is
thus assured for every shot.
