duce properly-exposed movies,

the needle remains in the red

area at the left side of the f/stop

scale (Fig. 19 ).

Movies made with the needle in

that position will be too dark,

underexposed. In extreme cases

of underexposure the film may

not even show an image.

To prevent underexposure, stop

making movies when the needle

touches or is in the red area on

the left side of the scale.

Do not make movies with the

camera pointed at the sun or

other bright light source. The

bright light will influence the

electric eye and make the pictures

too dark.

When the light is too bright, the

needle touches or enters the red

area on the right end of the scale

in the viewfinder. This may occur

when the camera is loaded with

fast film and is used in bright light

(in sunlight or under extremely

bright artificial illumination).

Movies made with the needle in

the red area on the right side of

the scale will be too light, over-

exposed (see "Neutral Density

Filter" section below).

To set the lens opening manually,

turn selector wheel clockwise,

toward "MANUAL", until needle in

viewfinder is over the desired

f/stop. Fig. 20, for example,

shows the lens opening set at f/8.

In the manual mode, use an ex-

posure meter to establish the

correct lens opening for the pre-

vailing light level. Set film speed

scale of exposure meter at ASA

speed of film (as indicated on film

box or in film instruction sheet),

then read lens opening at the 1/40

second shutter speed. Set the

camera lens opening 1.5 stops
