Naturally you must be guided by the deflection of the pointer. Too much light entering the meter will deflect the
pointer beyond the extreme right end. When there is too much light, snap the boaster shut and close the cover,
thus reducing light entrance. Unlike other exposure meters, the lack of Guide Lines has eliminated any
confusion in obtaining exact readings. The simplicity of just lining up the chaser bar and pointer gives an
immediate and accurate reading.
THE CALCULATOR OR
COMPUTER DIAL
This consists of three dials. The
manipulation of the dials is very
simple. You will find it easy to rotate
them to any setting, using your thumb.
FILM SPEED
This may be set by the calculator dial,
Film Speed Setting Dial for the ASA
or DIN value. You obtain either of
these values from the film
Manufactures leaflet accompanying the
film. Turn the dial so that the small
block mark an the edge of the ASA or
DIN window is opposite the
corresponding speed rating. Note that
there ore small divisions between the
ASA or DIN numbers for intermediate
values.
After setting the relative index (red,
blue or black) triangles aver the red dot
on disc, the calculator dial gives you
automatically all the exposure factors
needed for still, movie cameras, and
LVS or EVE shutters.
