A backlit subject, such
as
a person outside with hislher
back
to
the s
un
or indoors
in
front of a window, may
come out almost
as
a silhouette
if
the background
is
correctly exposed.
On
the other hand, if exposure com-
pensation is made
to
give the correct exposure for a
backlit subject, the background may
be
washed out.
To
fill
in
the shadows and balance the illumination levels of
the
subject and background,
you
can use
an
electronic
fla
sh unit even
in
daytime.
One important fact to remember
in
balancing the expo-
sure for both subject and background is thi
s:
Exposure
with
a flash unit
is
determined only
by
the aperture
selected, whereas exposure for ambient daylight
is
determined by a combination
of
shutter speed and
aperture.

Without flash or expo-
sure compensation:
the
backlit subject
comes out too dark.
Without flash,
but
with
the
exposure compen-
sation dial set
at
+2:
the
subject's face
is
correctly exposed,
but
the
background is
too
bright.
