"RED
EYE"
_ _ _ _ _ _
__ _ _ _ _
"
Red
eye
"
is
a
phenomenon
in flash photography
where
the
center portions of the subject's eyes
appear as
bright red
orbs in color
photographs
(or
white in black and white
pictures).
This
is a
result
of
the
light
from
the
flash
illuminating the retina
directly.
If
the
subject
looks
straight
into the lens
and
there is
little or no ambient light.
the pupil is
wide
open,
making
the retina
clearly
visible
in the
picture.
To
avoid
"red
eye,"
you can
take
any or all of the fol-
lowing
precautions:
1.
Ask
the subject not
to look directly into
the
lens
when
the picture is taken.
2.
Remove the
flash
unit
from
the
camera and
hold
it
as far away as
possible from the
camera
by using
a
sync
cord.
3.
Increase
the
room
's
overall illumination to reduce
the
opening of
the
subject's pupi ls.
TIPS ON SPEEDLIGHT CARE
_ _ _
_
•
To
remove
dirt
or fingerprints
,'
wipe with a
dry
soft or
si
licon-treated
cloth.
Never use
thinner,
benzine
or
alcohol, since they
might damage
the
plastiC
parts.
•
To prevent
damage to
the flash
unit's
electronic cir-
cuitry, keep
the
flash
unit
away from
places
where
the temperature is
likely
to
go
higher
than SO°C
(122°F),
such as inside
the
trunk of a car
in the hot
summer
sun; also do not store the unit
in
exception-
ally
damp
places.
Use the
S8-140 within
the range
of
-
1O°C(14°F)-+SO°C(122°F).
•
The UV
adapter
8W-SUV
is easily affected by
humidity.
8tore
the
8W-S
UV
with a desiccant or
in
a
well-ventilated
place.
•
If your
88-140 has not been used for
a long
time,
its
recycling time may be longer.
To
maintain the built-in
condenser
in peak
condition
,
there by
enabling
you
to use the 88-140 for many
years,
fire the flash unit
a few
times
every
month.
After
firing
,
wait
until
the
ready-light
lights,
then turn off the power
switch of
the
power
supply,
remove the
batteries,
and store
the
S8-140
in
a
suitable
location.
This
will prevent
the
condenser from
deteriorating.
•
Keep
the
flash
unit
away
from
salt water and out of
the rain
.
•
Never
attempt
to disassemble or rapair the
flash
yourself. These
delicate procedures
should
be left
to
an authorized service faci lity.
