color combinations for close-up work is very important. Try not
to have a large white expanse near a large black area. For instance,
a player in a white shirt or blouse against a dark background, or
beside a darkly dressed actor, will cause the white to run over
into the black. This is a fault of the television camera and not the
film camera. Whenever there is an abrupt change of color value
over large masses, it usually results in a smearing of one edge over
the other. For this reason, night scenes are not very satisfactory
since, due to the large amount of black or dark area around the
camera. Middle

grays reproduce best over the air, and a film which runs from
light to dark gray will give excellent results. The dark gray colors
will reproduce on the screen as a black, and the light gray will
appear as white as the color of the kinescope tube permits.

larger image is produced in the first place ; this, therefore, requires
less magnification, and more attention needs to be paid to scenery
details. The scene appearing in the view finder is the same with
either film. When watching the set through the view finder, there
are a number of items which require attention. If the scene is a
close-up, conditions of parallax error may occur. These are caused
by the fact that the axis of the view-finder lens is displaced a few
inches from the axis of the camera lens. At distances of over a few
feet, this is not important because the field covered is about the
same for either lens. However, for close-ups of only a comparatively
few inches, the difference in area covered may well be
sufficient to spoil a shot. This is shown more clearly in Figure
11-2 A and B where the fields from both lenses are indicated by
crosshatching. In the first figure the two areas overlap, but in the
second the close-up the subject would be displaced to one side
and the composition of the scene ruined. The various makers of
cameras have their own particular versions of view finder. In
many of the three-lens turret cameras a complementary three-lens
view finder is used. This makes it necessary to remember to select
