When
two flash units are the same distance from the
subject and face approximately the same direction, the
combined
GN
of the two units can
be
determined with
the following equation:
Combined
GN
= V
GN
14GN22
(GN
1
and
2 are the guide numbers of the flash units.)
•
When
using two flash units facing the same direction in either the
TTL
mode
or
one
of
the manual modes, compensate as follows according
to
the equipment
in
use:
1)
With
two S8-103 Speedlights: select an aperture one step smaller
(a
numerically larger f-number) than that shown
in
the exposure
calculation chart.
For example, when the fl stop shown in the exposure calculation
chart
is
f14
, reset the aperture
to
fI5.6.
2)
With
one S8-103 and one S8-102 Speedlight: select an aperture
two steps smaller
(a numerically larger f-number) than that shown
in
the exposure calculation chart.
For example, when the flstop shown in the exposure calculation
chart
is
f/4,
reset the aperture
to
fIB.
•
When
using manual flash operation, set each speedlight's shooting
mode selector/power switch
to
the same position, for example,
"M
114
."
To
use them at different positions, first calculate the combined
GN from the equation formula above, then determine the correct
aperture from the combined GN.

When shooting
in
daylight, a backlit subject may come
out almost
as
a silhouette if the background
is
correctly
exposed.
If,
on
the other hand, exposure compensation •
is
made to correctly expose the subject, the background
may
be
washed out.
To
fill
in
the shadows and balance
the illumination levels of the subject and the background
in
daylight shooting, use daylight fill-in flash photography.
When using the Nikonos-V, its viewfinder
LED
indicator
will blink to indicate the correct shutter speed under
natural lighting.
To
obtain the correct exposure with
daylight fill-in flash shooting, turn
on
the flash unit and
select progressively smaller
flstops
(numerically larger
f/numbers) until the camera's 1/125 second and 1/60
second
LEDs
begin blinking or until either the 1/60
second or the 1/30 second
LED
indicator blinks. Make
sure the subject
is
within the coupling distance range
and, if the viewfinder ready-light
is
lighted, release the
shutter.
