Project AP-3 Analyze Lighting (see Light Notes below)
Project Analyze a film for the elements of lighting. In documentary you can’t always control lighting; instead you control camera angle, composition, and exposure parameters to capitalize on what’s present. Here’s an exercise in recognizing the elements you must work with. In controlled documentary—a historical recreation, say—you would have the time and facilities to deliberate over using such lighting techniques.Goals are to identify examples of:a) High contrast, low contrast imagesb) Graduated tonality imagec) Practical lightsd) Fill lighte) High key and low key lighting situationsf) Hard (specular) light and soft lightg) Portrait shot with frontal lightingh) “ “ “ broad lightingi) “ “ “ narrow lightingj) “ “ “ backlightingk) “ “ in silhouette
Preparationa) Pick a documentary with a variety of lighting situations (interior/exterior,
day/night, artificial light/sunlight, etc). My choice is______________________________(title)
b) Identify one or more of the facets specified in (a) to (j) above, using a computer frame-grab facility to collect samples that you integrate into a piece of explanatory writing.
Writing Describe and append a sketch if it helps,a. What the film delivers as mood, message, meaningb. What makes each of your shots qualify in (a) to (j) lighting categoriesc. Where the key light originates in each shot (for example, a window or a
fluorescent overhead light, or supposedly from a table lamp “practical”)
d. What feeling the particular lighting contributes to each scenee. What progression the lighting follows through the filmf. Discuss what you learned from making this analysis, and what resolutions you
formed in relation to your own filmmaking
Notes Shooting spontaneously means taking advantage of the lighting and compositional potential of any scene. You’ll need a practiced eye and a keen mind to realize all that’s on offer. During your analysis try to distinguish between lighting applied by the filmmakers and shooting that makes artful use of circumstances. Shooting under available light is mostly the latter, though a fill light mounted on the camera sometimes makes a vital contribution to lighting.
Alternative: Using a digital camera, shoot documentary stills as examples.

Lighting NotesThis project challenges you to categorize types and combinations of lighting situation,
become familiar with the look and effect of each, and be able to use the appropriate
terminology in describing them. The aim is to recognize the emotional associations that
all the different possibilities that lighting and image control bring to our art.
When you do your lighting study, turn down the color control on your monitor until you
have a black-and-white image uncomplicated by chrominance. What follows is a just a
brief rundown; you will need a lighting text to go deeper. YouTube and other web sites
offer many lighting demonstrations, but mostly for still photography. I like
www.youtube.com/watch?v=9KZe7Xbi6DM for the way it works in black and white and
demonstrates the effect of each source light as it goes.
My illustrations are frame-grabs from Tod Lending’s Omar and Pete (USA, 2005,
www.nomadicpix.com) shot by the masterly Slawomir Grunberg. The film’s first 12
minutes are available to watch on this book’s website
(www.directingthedocumentary.com). It chronicles attempts by the prison system to
rehabilitate recidivists—the hard core who keep returning to prison. Through two such
men it examines the Gordian knot of social disadvantage, racism, poverty, poor
education, and dysfunctional family life that lie behind the tragic self-destruction of so
many African American men. Grunberg’s camera handling and special picture quality set
us deep within a grim world from which there is little escape.
LIGHT SOURCES: KEY, FILL, BACKLIGHT, PRACTICALS
Key light is the source casting the shot’s shadows. The key light on Omar’s sister in her
office comes from the window behind her and off to the left. The rest of her face is
illuminated by fill light.
Fill light illuminates shadow areas so that a camera can record their detail. In Figure AP-
3A fill comes from soft light (see below) cast either by a fixture close to the camera, or
by window light reflecting from the office’s white walls. In exterior shots you often
throw fill light on the subject using handheld reflectors of silver or matte white. Fill is
necessary because highlights under sunlight are often so bright that important shadow
details, such as in a person’s eye-sockets, remain in deep shadow. By adding light to the
shadow areas you lower the contrast (see below) between highlight and shadow areas so
the recording medium can record detail in each.
Back light is a source shining on the subject from behind, and often from above. Also
called a hair- or a kicker-light, it casts a rim of light around a subject’s head and
shoulders, and creates a separation between the subject and background, as seen here
with the two men on Omar’s parole board.
A practical is any light source that appears in frame as part of the scene, such as a
bedside light, miner’s lamp, or traffic signal. The fluorescent fixture above Omar and his
guard is a practical. Most practicals don’t supply light for exposure, but Omar and Pete
was shot in prison under available light, so they supplied most of the lighting.
Set lighting is that needed to adjust a scene’s background to a proper illumination level.
TONALITY
A high-key picture looks overall bright with small areas of shadow. Any shot, interior or
exterior, can be overall bright and thus qualify as high key. Comedies are mostly high
key, while film noir is by definition low key. Every film needs relief from its
predominating mood, and exteriors provide the audience with reprieve in Omar and Pete.
A low-key picture is one that looks overall dark with few highlight areas. Low key
images, often interiors or night shots, predominate in Omar and Pete. This is the cage of
steel surrounding Omar. The system offers him the opportunity to work his way out, but
can he do it?
Graduated tonality shots have neither very bright highlights nor deep shadow, but consist
mainly of midtones—a term referring not to colors, but the tonal range between dark and
light. Here Omar seems to blend into the detention facilities that contain him.
CONTRAST
High-contrast pictures have a big difference between highlight and shadow illumination
levels. Here, birds have the liberty that an imprisoned man can only dream of, and their
world is in stark contrast to his own.
Low-contrast pictures can either be high or low key but their highlight levels are not far
above their shadow illumination. Notice how selective focus in this case isolates and
separates Omar from his background, unlike Figure AP-3F.
LIGHT QUALITY
Hard lighting describes light quality in terms of its shadow. Hard light or specular light
creates hard-edged shadows (for example, a studio spotlight, a candle flame, or sunlight
as in the Figure AP-3I). Hard light is not necessarily strong light, just light coming from
an effectively small source whose rays cast distinct shadows.
Soft light comes from an effectively large source and creates soft-edged shadows (for
example, fluorescent fixtures, sunlight reflecting off a matte-finish wall, light from an
overcast sky, studio softlight). In this shot there is some shadow under the subject’s chin
and beard, but it’s very indistinct.
TYPES OF LIGHTING SETUP
Photography’s limitation is that you must use a two-dimensional medium to present a
three-dimensional world. What’s missing is depth, so in portraiture you use angled
lighting to reveal the third dimension. The basic portrait lighting setup is called three
point lighting and its components are diagrammed in Figure AP-3K. It uses a fill light, a
key, and a backlight. There’s also set lighting which illuminates the background and
which we’ll leave aside.
In the diagram only the fill light is turned on; it emits disorganized light rays from a
broad source that casts little shadow. Keeping it close to, and above, the camera means
that any shadow it does cast is largely thrown behind the subject and out of sight of the
camera.
This shows a face lit by fill light alone. Once you turn on the key, it will illuminate the
other side of the face and cast definite shadows. By moving the key through positions A,
B, and C we create three classifications of lighting.
Frontal lighting setups have the key light in position A, close to the camera/subject axis,
so that shadows are largely thrown backward out of the camera’s view.
Broad lighting setups have the key light in position B so that a broad area of the subject’s
face and body is highlighted by the key.
Narrow lighting setups have the key light in position C to the side of the subject, and
perhaps even beyond, so that only a narrow portion of the face receives highlighting.
Most of the face is in shadow and depends on fill for an exposure.
Calculate lighting ratio by measuring light reflected in the highlight area and comparing
it with that from the fill area. When taking measurements remember that fill light reaches
the highlight area but not vice versa, so you can only take accurate readings with all
lights on.
Back lighting setups have the key light coming from above and behind the subject,
picking out the body outline and putting highlights in the hair and profile. Some
additional fill would make this an acceptable lighting setup for an interview.
In silhouette lighting the subject reflects no light at all and shows up as an outline against
raw light. This setup is useful when the subject’s identity must be withheld.
