have enough base light. A higher base light allows you to work with smaller
lens iris openings which increases depth of field, making it easier to focus.
b. When lighting large groups of people, such as commanders' calls or
chaplains' briefings, the easiest and most efficient method to light is by
establishing a general, nondirectional base light.
Simply use two or three
portable lights and bounce the illumination emitted by them off the ceiling or
walls. If this is not possible, direct the light on the group but diffuse the
light with scrims.
The most efficient method is to use two or three small,
high intensity lights, such as tota-lights and diffuse their beam with
umbrellas (fig 3-4).
Lighting a large group
4. When time and equipment are available, the same basic lighting principles
are used in field lighting as are used in the studio. If you refer to Figure
3-5, you see three-point lighting set up the same way it would be set up in the
studio. In this situation, however, the portable lights are of a type that can
be placed in either the spot or flood position. This lighting also shows the
use of a background light.
