The LEICAMETER MC must be set to the speed rating

of the film being used. It has two built-in measuring

ranges (indicated by black and red dots on the

instrument) and a third range, for extremely low

illumination, is obtained by means of an accessory

booster-cell (see special instructions). Direct exposure

readings may be obtained in two different ways: (1) Set

the desired shutter speed opposite the black triangle

on lop of the meter. Observe the aperture indicated by

the moving pointer-needle, and set the lens aperture

scale accordingly. (2) Set the desired lens aperture and

turn the milled meter adjustment wheel until this

aperture on the meter dial appears opposite the moving

pointer-needle; the correct shutter speed is

automatically set. If there isn't enough light to obtain a

reading on the black aperture scale, set the range-

selector to the red dot and use the red scale of

apertures. Note that the first two openings on the red

scale (f/1.5 and f/2) overlap the last two on the black

scale (f/11 and f/16). The correct value is, determined by

the position of the range selector lever.

The diffuslng-screen for incident-light readings attaches to the front of the

meter and shows its presence by a protruding tab. See special instructions

in the LEICAMETER MC manual before attempting to use this measuring

technique.

For exposure times from 2 to 120 seconds turn the milled meter setting ring

to "B", then lift up to uncouple before turning further in the direction of the

arrow (at the right-hand side of the meter). The reading is made as

described above except that the shutter-release must be held down

(preferably with a locking cable-release) for the total time required. For

booster-cell readings first observe the shutter speed opposite the small

square symbol, then set this speed opposite the black triangle before

exposing. Remember that the black triangle on top of the LEICAMETER

MC always shows the speed at which the shutter is set. In the illustration

above you will notice that the shutter is set at

250

sec., while the square

symbol appears opposite

sec. Had this reading been made with the

booster-cell it would be necessary to transfer the

sec. to the black

triangle.
