Lighting Locations
Few video productions are shot on
soundstages (except those made for theaters,
cable, or broadcast), so your interiors are likely to
be locations. Every location presents challenges,
and meeting them offers the satisfaction that
comes from successful problem solving.
Small Interiors
Small interiors are usually difficult to work fi
in, for several reasons (Figure 16-12).
Cramped Quarters
Lights require room, not only for the
instruments and stands, but for the throws
of the lights. Remember: you reduce light
intensity mainly by moving the unit away
from the subject. Spots and broads are favored
for cramped interiors because of their small
size. Spots are especially useful in tight
quarters because they can be focused to vary
the light output without moving the unit.
Their intensity can be further reduced by
using screens.
Power Supplies
Small interiors are often located in
homes or other private buildings where
electrical circuits are typically only 15 amps,
and an entire room may be served by just
one circuit. When working with inadequate
power, high-efficiency LED and fluorescent
lamps draw less power per unit output than
halogens. With CFLs (compact fluorescent
lights) and LEDs, medium screw-base units
can put out up to 3,000 lumens of light,
Figure 16-13.
Background Spill
Small interiors make it diffi to keep ficult
subject light from spilling onto the background.
Here again, using the more controllable spots
and broads can help minimize the problem.
