fi
ll
-in lighting.
(See "Balanced fill-flash.")

The timing of the flash
so
it
fires coincident with the operation
of the camera's shutter.

Changing one step to the next larger
number
(Le.,
from
1111
to
1116)
decreases image brightness by
1/2; moving
to
nearest lower number doubles the brightness.
Guide number
The number given to a flash bulb
or
electronic flash unit
to
indicate its power. A guide number may be quoted
in
meters
or
feet,
and depends on the speed of the film being used.
Guide numbers quoted assuming a relatively efficient reflector
surrounds the flash source, e.
g.
, an average-sized room.
ISO film speed
The international standard for representing
fi
lm sensitivity
(speed with which
it
reacts to light). The higher the number, the
greater the sensitivity, and vice versa. A film speed of
ISO
200
is
twice
as
fast as
ISO
100,
and half the speed of
ISO
400 film.

For
the N5005, used to provide indica-
tions inside the viewfinder and self-timer indication.

is
an exclusive Nikon feature.
