Film lighting tips

Avoid the flat look, regardless of
whether you’re shooting an
interview
or an ambitious epic. Avoid lighting
your subject directly from the
front with a single light source.
A popular technique in professional
lighting is to use a soft (diffuse)
light source from the front and a
stronger, more directional light from
the back, so that your subject has a
hot edge. The soft frontal light is
known as the fill light; the strong
light at the back is known,
unsurprisingly, as the backlight.
You can arrange the lights in such a
way as to leave darkness between
the area illuminated by the backlight
and the area illuminated by the
fill light, depending on how moody
you want the shot to be. This tends
to work very well, although even the moodiest films tend to avoid
leaving dark shadows on the faces
of female talent.
For a slightly different look, the
backlight can also be soft, but it
should still be hotter than the fill.
You should light your film or video
shot by shot. This means that when
you relocate the camera to shoot a
different angle, the lights must be
moved as well to ensure the subject
is always lit correctly. This is
partly why films take so long to
shoot.
Setting up lights is the most
time-consuming task in film shoots.
It is
therefore good practice to shoot a
scene in such a way as to minimize
the need to relocate lights – in other
words, shoot in the order of the
lighting set-ups.
Here’s a trick that can save huge
amounts of time: when covering a
scene
with a shot and reverse shot,
instead of moving the camera and
lights
for the reverse shot, simply switch
the actors around and move the
camera to the other side of the
eye-line, in order to maintain the
correct eye-line relationship. This
allows you to use the same lighting
set-up for two or more pairs of
shots. Depending on the situation, it
may help to move some props
around too. It generally works best
when the
backgrounds of the two actors
cannot be distinguished. This
technique is
not always appropriate, but in the
right situation it can be totally
convincing and a huge time-saver.
