and back light for easy indoor filming

THE-, first and most obvious purpose of any lighting unit in interior filming is to throw enough light on the subject to create adequate exposure. This is not, these days, a difficult operation. We find, for example, that only two RFL-2 lamps (the built-in reflector type) placed six feet from the subject create an exposure of f/2.8 with indoor color film. Two regular No. 2 flood bulbs in efficient metal reflectors at the same distance return
an exposure of f/3.5.
