function
,
it
is
helpful when using daylight fill-in flash
shooting.
Shooting Mode Selector/Power Switch
®
The shooting mode selector/power
switch
has five c!ick-
stop
settings.
The
shooting
modes that can be
used
with
specific cameras
are listed
above.
"OFF"
position
The speedlight
is
turned
off when
the switch is
set at
this
position
.
"TTL"
position-TTL (through·the·lens) Automatic
Flash Mode
This mode, which
can
be used only in conjunction
with
the Nikonos-V camera, automatically controls the
flash
exposure
Through·The·Lens
(TTL).
In
this mode, the
Nikonos-V's SPD
(silicon
photodiode) reads the light
passing through the lens and automatically signals the
S8
-103 to turn itself
off when
the
exposure is correct.

The range of useable apertures is
larger
(from
f/2 .8
to
f/22 when using
ASAIISO
100 film) with TTL flash
,
and
you can easily
control
the depth
of
field
.
In
addition
,
the
TTL
mode makes daylight fill
-in
flash and close
-up
photography easier than
ever.
o
The
useable
film speed range for TTL operation
is
from
ASA/
ISO
25
to
400.
For information about the
apertures
that can be used at
various
film
speeds, see
page
