USING YOUR CAMERA'S
EXPOSURE METER
Your Cosmorex SE incorporates a sensitive built-
in Exposure Meter. It contains a photoelectric (
selenium) cell (25) that converts the light
reflected by your subject into electrical energy,
which activates the Meter Needle (17). Because
the "selenium" meter cell generates its own
electrical energy, no batteries are needed! Here's
how to use your exposure meter:
1. Adjust Meter for ASA Film Speed. Move the
Aperture Indicator Dial (20) until the ASA
number for your film type is shown by the
black Index Mark in the ASA film
Speed Indicator Window (19).
Your camera's meter has marked numer
als for films rated at ASA 25, 50, 100, 200,
400, and 500: this speed range encompasses
virtually all general-purpose black-and-white
and color films. Should your film be rated at
an intermediate ASA speed, such as ASA 64 or
80, simply position the ASA Index Mark so
that it is between the next larger and smaller
numbers. (For example, for ASA 64 or 80
film position the index mark
`
been 50 and 100.) When this is done, your
meter will operate well within the tolerances of
all film types.
NOTE: If you are using film marked only in "
DIN" (European) film speed, enter this number
in the DIN Film Speed Indicator (18). Should
the film be marked in an intermediate speed
number, position indicator midway between
the next larger and smaller numbers as describe
d above.
