of
the
scene
with
medium
contrast,
to
set
the
diaphragm
accord-
ingly,
and
only
then
to
frame
the
picture
as
desired.
The
converse
precaution
may
prove
necessary
on
a
snowfield
if
the
sun's
glare
is
particulariy
strong.
Dark backgrounds
When
the
subject
in
the
foreground
is
particularly
bright
against
a
dark
background,
the
main
subject
risks
overexposure.
In
such
cases,
the
light
value
should
be
measured
before
filming
by
bringing
the
camera
as
close
as
possible
to
the
subject
or
by
setting
the
zoom
lens
to
“telephoto”,
so
that
the
main
subject
occupies
the
major
of
the
field.
Once
the
aperture
is
set,
come
back
to
the
filming
position
and
frame
the
scene
as
desired.
Intense
source
of
light
in
the
field
A
bright
electric
light,
a
brilliantly-lit
window,
must
be
left
outside
the
field
when
measuring
light
intensity.
Filming against the light
Unless
systematically
aiming
at
a
dark
silhouette
effect
against
a
light
background,
details
of
the
subject
can
be
obtained
by
measuring
light
intensity
on
a
shaded
part
of
the
subject
(lens
set
to
maximum
focal
length
and
light
measured
as
close
as
possible
supplied
with
every
camera
(44).
