"RED
EYE~-'I
-----
"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
follow-
ing
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 froin
the
camera
by
using
a sync
cord
.
3.
Increase
the
room's overall illumination to
reduce
the
opening
of
the
subject's
pupils.
