(2) In silhouette lighting, you use highly diffused light (usually from
scoops with scrims or soft lights) to get the background evenly illuminated.
c. Color background lighting. To change the colors of the set background,
you can use various color gels to add or change the color of the background.
(1) For example, if you want a background of an even red color, you
would "gel" all the background scoops with red colored gels. If you wish to
break up your neutrally-colored background, you could gel a few background
spotlights with the appropriate blue-colored gels.
(2) By using several sets of background lights (several instruments
grouped together) with different color gels for each set, you can easily change
background colors by dissolving from one set (on group dimmer 1) to another (on
group dimmer 2).
(3) When lighting the background at a set, it is best if the
illumination for the background comes from the same general direction as the
key light. Further, the background light should be about half as bright as the
key light (key to background ratio 2:1).
d. The chroma key set area consists of a colored background (normally
blue) and the foreground area, such as a newscaster's desk or interview chairs
and table.
The blue background is used for chroma key matting.
That is
placing the picture from another source into the scene electronically.
Wherever the color blue is within that scene, the picture would be inserted.
(1) The most important aspect of lighting the chroma key set area is
even background illumination.
In order to achieve an optimally effective
chroma key matte, (electronically supplied background image), the blue
background must be lighted with highly diffused instruments, such as soft
lights or scoops with scrim attachments.
(2) If there are hot spots (undesirable concentrations of light in one
spot) on the blue background or unusually dark areas, the matte looks
discolored, or worse, has a tendency to break up. When lighting the foreground
set, make sure there are no spotlight beams hitting the background area so that
you can preserve the evenness of the chroma key background illumination.

DEFINE AND DESCRIBE STUDIO LIGHTING EQUIPMENT
1. In order to accomplish studio lighting, we must have equipment available
that is functional and easy to use.
Great strides have been made over the
years to improve the reliability and operational ease of lighting equipment.
Studio lighting equipment is defined as the lighting instruments and
accessories necessary to accomplish studio lighting.
