shutter speeds and  f/stops  (with  the
exceptionof the maximum apertureson
certainlenses).                                6) Filter Factors
Example: You wish  to  take a  picture   Exposure factors caused by  filters are
with an ASA 12 film at a shutter speed   automatically compensated for  by  the
of 1/1 000 second. The fastest possible   behind-the-lens  CdS  meter  system,
shutter speed is 1 /500 second. Assum -    except for certain red filters.
ing the correct f/stop with 1/5OO second
is f/5.6, you simply open the apertureto
t 14 and set the shutter speed to  the
desired1 /1 000 second.
lf the shutter speed exceeds 1 second,
you can easily determine the exposure
based on  the ASA  film speed rating.
Example: You wish  to  take a  picture
with a 25 ASA film. The lens is set at
full aperture and the shutter speed at
1 second, but the needle still cannot be
centered. Change the ASA  setting on
your dial until the needle is centered.
Assuming that  it indicates 100 ASA, i.e.
2 stops above your film speed of 25
ASA, yo u  easily determine the  exact
shutterspeed of 4 seconds.

5) Battery Change
lf the needle no longer moves, while
you  depress the  release butto n,  the
batterieshave to be changed. Make sure
there is no  film  inside your ALPA-
(counter must be 3 numbers below 0,
see page 6)-and  remove the camera
back. U nscrew the large lid of the bat-
tery housing at the bottom with a coin.
