mark in the window. The first mark

represents the 80° opening setting;

the second the 40° setting. When the

edge of the red indicator reaches the

bottom end of the window, the shut¬

The manual use of the shutter blade

opening control shpuld be avoided

except for the 80° or 40° setting.

Ekposure Compensation

When the angle of the shutter open¬

ing is altered, the lens aperture must

be adjusted to compensate for the

change. The table below gives the

exposure

compensation

for

each

opening. To compensate, turn the

adjustment control until the white

line is opposite the appropriate num¬

Exposure Control with Running

Speeds

The different running speeds of the

camera provide further hieans of

exposure control since the exposure

time is inversely proportional to the

camera

speed:

the

exposure

per

frame at 18 fps is three times as long

as at 54 fps. Since films are usually

shot at 18 fps, do not use this

method of exposure control except

for special effects.
