Advantages of the system
• Compactness of the measuring assembly
and display situated next to the ground glass
This lay out requires the minimum of optical
components, no reflection, no intermediate
optics, (no risk of misalignment).

INSTRUCTIONS FOR USE:
1° Setting up:
• Connect the battery to the camera.
• Look in the viewfinder to make sure the cam-
era is in viewing position (mirror in front of
aperture).
• Move the switch (32) to the right. The diodes
will light up (camera stopped).

Determine with your. light meter, the
setting of your diaphragm taking into account
the speed of the emulsion and the filming
speed.
• Adjust your lens according to the setting
indicated by your light meter (f. 5.6 for example).
• Looking through the viewfinder, turn with one
finger of the right hand the sensitivity potentiom-
eter 34 one way or the other so that only the
central diode lights up. This being done, your
camera is now set up.

2° Filming
Obviously, for keeping a normal expo-
sure, the central diode only must be lighted. If
the lighting intensity of the object varies, the
control diodes will be seen lit up either + or -,
visible in the viewfinder; this will indicate that
you overexpose or underexpose. The operator
will then adjust his diaphragm by closing or
opening it accordingly to come back to the
normal exposure which will be shown by the
illumination of the central diode only. In effect
the operator has a continuous indication of light
variations to within plus or minus 1 1/2 stops
from the normal exposure and which he can
vary at will (eg. for contrast effects).
