(1) The ellipsoidal spotlight can also be used as a pattern projector.
In this case, the ellipsoidal spotlight has a slot in its housing next to the
beam-shaping shutters which can hold a metal pattern called a cucalorus or more
simply a cookie.
The ellipsoidal spotlight projects the cookie as a clear
shadow pattern on any surface.
(2) The ellipsoidal spotlight is generally used for specific, precise
lighting tasks, rather than for standard television lighting.
c. Another type of spotlight that is sometimes used in the studio is the
follow spotlight.
This type of lighting instrument is a powerful, special
effects spotlight that is primarily to simulate theater or stage effects. The
follow "spot" allows you to simultaneously pan (move the light left or right)
and title (move the light up and down).
The follow spot is used to follow
action, such as dancers on a stage or single performers moving about in front
of a stage curtain.
3. Floodlights are designed to produce a great amount of diffused light. They
are primarily used to slow down the rate of falloff, reduce shadow density, and
to provide base light.
a. The most common and popular type of floodlight used is known as the
scoop because of its shape (fig 1-9).
It is a very versatile lighting
instrument that can hold colored gels, which are used to change the color of
the light, or scrims, which are used to further diffuse the light and reduce
its intensity.
