(or brightness) is
the actual amount of light. Focused or defused light can be
produced in various intensities or amounts of brightness.
"Hard light" is a
concentrated light originating form a single point source. This
single stream of light produces sharp or "hard" shadows. Hard light may be a problem when shooting, or it
maybe the solution for a desired effect. The sun on a sunny day produces very hard light, as does a
projector, spot light or even a flashlight. The effects of Hard
light is sometimes a desired type of light in scary scenes/movies
to produce deep shadows. It is obviously the type of light used,
especially on stage to focus everyone's attention on a subject, the
host or singer of a show for example.
results when the source of light is defused.
This type of light results in less
defined shadows--or perhaps even eliminating shadows. The fluorescent
lights in our classroom
produces a type of soft light. Similarly; clouds on a
cloudy day defuse the sunlight. When you get your school
picture done, the photographer uses umbrellas to soften the shadows
on your face. A
scoop is a common means of
producing a soft light in film and theatre.
One type of light
that is very much used on stage and in film is the
That is because it has a sliding adjustment that allows the light,
when slid to the back, to be a hard focused beam of light on a
Barn doors block light from a certain area which indirectly
helps to harden the light source. As you slide the adjustment
towards the front the light becomes more and more defused to an
eventually somewhat soft light in comparison. To soften the
light even more, one can add a
special non flammable, porous white material) to filter the light.
An other way to soften the shadows on a subject, no matter the light source, is to use a bounce card. A bounce card can be something as simple as a white bristle board or even a cookie sheet to deflect some light back onto the subject from the shadowy side.
"Color of light"
- One way to visually understand the
difference in colour of light is on the highway at night when we
meet cars with different colour headlights. The actual light
produced by the bulbs are not coloured , yet we can clearly
distinguish between LED and regular incandescent headlights. LED
lights look blueish, while incandescent look yellow/reddish in
comparison. Just like newer Christmas LED lights, LED headlights are
said to produce a natural colour light. Blue like sun light. While
incandescent lighting, like candle light, has a more fiery colour.
Obviously one can make the light look any colour of light by adding
coloured lenses, or as in film and theater
used to for different colour effects.
Generally speaking; when filming the colour of light depends on the 3 main sources that usually produce the light.
< Natural sunlight produces a blue light
< Incandescent light that comes from old light bulbs, (flame produced light) gives light a reddish hue
< Florescent lighting is green in color
Balance" Our brains are able to
adjust to the different colours of light
in a way that they all look the same to us. A camera may need help
to figure out the difference. It is important to know how to help
the camera distinguish between the influence of the various hues of
colour in the picture resulting from the various light sources for
the best picture. This is especially important when editing
different clips together from different times and sources.
To insure proper and constant colour in
you footage, you should set the white balance.
When shooting interviews and/or scenes on stage for example; the common light setup used is:
3 light setup":
"The key Light" is the brightest light source and is positioned app. 45 degrees to the left or right of the subject.
"The fill Light" is a light source positioned app. 45 degrees from the opposite side of the subject, and less intensity than the key.
"The backfill Light" is

> Use a bounce card to act as fill light source
> Use artificial light as a stronger fill light source
> Move to shadier site

(especially for skits or when doing animations)
> Use umbrellas for close-ups
> bounce cards for close-ups, or bounce the light off the ceiling for long shots
> Try using scoops
> Put a scrim over a hard light source
> Make use of the 3 light setup
> distance your props and subject from any backdrops

(or the color balance button as some brands call it) - converts coloured light into true colour.
If your camera is being fooled and you need to set your camera, you can do so by zooming or focusing in on something white card like a white "T" shirt or some other white object). Professionals use a white card (bristle board would do). Simply fill your screen at least 20% and hold the white balance button for a couple of seconds and you are good to go.
Light has 3 main characteristics:
-Type, either hard or soft
- color, 3 general colors are white, bluish and orangey/reddish
In a way, all three characteristics are determined by the light source.

Which is the commonly used unit of measure for the amount of energy
consumed by a television lighting instrument?
The color of the light coming from a candle is:
A) Create harder light
B) Create softer light
C) Protect the lamp
D) Make the light brighter
E) “Zoom” in on the subject.

Soften shadows created by the back light
Minimize shadows caused by the key light
Provide the primary illumination of the object
