P-Programmed Exposure Mode - Nikon FG Instruction Manual

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.
