Non·TTL Automatic Flash Exposure Compensation
When
shooting
in the non-TTL automatic flash exposure
mode, exposure
compensation
can be made by
stop-
ping down or opening up the
lens.
To compensate for
a dark subject
,
use
a
1/2-
to 2-step smaller
aperture
(a
numerically larger
f-number).
To compensate for a
light subject,
use
a
1/2- to
2-step
larger aperture (a
numerically
smaller
f-number).
•
The
ready-light will light up when the S8-102 has recycled
to
80
%
of
its full capacity. Therefore, if you want to shoot
a
subject at either the
minimum or maximum camera-to -subject coupling
distance
in the
non- TTL automatic mode or one of the manual
modes,
it
is
best to wait
until
a
few seconds after
the ready-light has
lighted.
o
As
the voltage of the
batteries decreases
with
use,
the GN of
the
flash
unit decreases
slightly.
o
The voltage of NiCd batteries decreases rapidly when their power
is
almost
exhausted,
increasing the recycling
time.
When
this
occurs,
stop using them immediately and recharge them or they may be
damaged.
o
When using alkaline-manganese
batteries,
if recycling takes 30
seconds or
longer,
replace the batteries with
a
fresh set.
o
The
ready-light goes out when the flash unit is turned off.
o
When
the exposure meters of the Nikonos-Vand Nikonos
IV-A
are not
activated,
the cameras
'
viewfinder ready-lights will not light even
if
the
speedlight
is
turned on (except when the shutter speed/mode selector
dial or shutter speed dial
is
set at
M90
or
M).
Always
confirm that the
viewfinder ready-light
is
lighted before
shooting.
o
When the shutter speed/mode selector dial or shutter speed
dial
of the
Nikonos-Vor Nikonos IV-A
is
set at
M90
or
M,
the viewfinder ready-light
lights when the flash unit's ready-light lights.
Ready-Light
®
After its power switch is turned on, the ready-light on
the 8B-102 will light to indicate that the 8B-102 has re
-
cycled and is ready to fire. If you are using either a
Nikonos-V or Nikonos IV-A camera
,
its viewfinder ready-
light will also light at the same time to let you know the
flash unit is ready for the next shot.
In addition, the viewfinder ready-lights of the
Nikonos-V
and Nikonos IV-A blink to warn of improper
settings.
If
this
happens,
check that the camera and flash unit are
securely connected
,
and the shutter
speed/shooting
mode and A8A/180 film speed on the camera are
correctly set.
Warning Function: Beyond Auto Shooting
Range
In the TTL and non
-TTL
automatic
modes,
the ready-
lights on the flash unit and in the camera 's viewfinder
blink for
approximately
2 seconds if the flash un it has
fired at its maximum output
to
indicate that the light
output may not have been
sufficient
for correct expo-
sure. If this happens, recheck the flash-to -subject dis-
tance
.
If it is beyond the coupling distance
range,
use
a larger aperture (a numerically smaller f-number), if
possible
,
or move closer to the subject.
Because the voltage of batteries (especially alkaline-
manganese batteries) decrease rapidly with
use,
the
GN of the flash unit will decrease
slightly.
The flash
output of the 8B -102 also varies according to the
amount of ambient light and the subject's
reflectivity.
