PRINCIPLES OF MOVIES 21
dub-in The process of adding sound to the film after the film has
been made. It has also come to mean the addition of anything
after the original has been made.
edge flare An unwanted light produced by the spurious emission
of electrons due to the action of the scanning beam in the
film camera tube. It can be reduced by using film that does
not have black areas at the edges. It may
also be countered
by edge lighting which consists of a small lamp illuminating
the edge of the mosaic.
elevation A vertical sketch of the stage and settings to show the
detail in the vertical plane.
establishing shot A very important shot in any film for television,

scene in one shot, just as though the viewer were standing

a form of silver halide suspended in gelatin, for black and

change in the intensity of the picture. In a jade-out, the picture
grows gradually darker until the screen is black, in a
fade-in, the picture gradually appears out of the darkness.
fade to black A favorite method of ending a television play, or a
film. The picture is gradually faded down until the screen is
black. In television, it is done electronically; in motion pic-

feature The term used to describe the main event of a program.
A feature film is usually at least 9000 feet long (35 mm).
field Optical-program, the area covered by the lens of the
camera and therefore recorded on the film or the television
screen. Electronic-optical, one set of scanning lines. In the
U. S. system of television, the scene to be televised is scanned
twice by the camera for each complete picture. The first time
