SETTING THE FILM SPEED
Each type of film - color or black & white -has its own sensitivity to light. This sensitivity
is assigned a numerical value described as an
ASA rating (U.S.A. Standard) or a DIN rating
(Europe and most other countries). In most
cases, both ASA and DIN ratings are imprinted
on the film package, as well as the data sheet
packed with the  f ilm and the  f ilm cassette
itself  .
The higher the film speed rating, the more
sensitive the film is to light that is, less light  is
required for a proper exposure. The  f ilm speed,
therefore, is an important element in ensuring
that the through-the-lens metering systems of
your camera determine the correct shutter
speed/ft*top combinations for a given lighting
situation.
Each time a film with a new film speed rating is
loaded in the camera, the film speed MUST be
set in the Film Speed Window (8) to assure
accurately exposed photographs.
To set the film speed:
1. Lift up on the outer collar of the Shutter
   Speed Dial (10) and rotate it until the ASA
   number or representative index mark  is
   opposite the green index line.
2. Release the collar to lock the film speed
    setting in the camera.
The film speed range is from ASA 25-3200.

SETTING THE SHUTTER SPEED
The shutter controls the length of time light  is
allowed to strike the film. The speed at which
the shutter opens and closes is measured  in
fractions of a second that correspond to the
numbers on the Shutter Speed Dial (10). For
example 1000 is 1/1000 second, 125 is 11125
second, 2 is 112 second, and so on. The number
"1" on the Dial represents one full second of
exposure. When set to "8" (Bulb) the shutter
remains open as long as the Shutter Release
Button is depressed. This setting is for use in
pictures of night scenes and where available
light exposures are beyond the exposure read-
ing capabilities of your camera.
To set the shutter speed, rotate the Dial until
the number representing the speed you desire is
opposite the index mark. Generally speaking,
when outdoors in bright or hazy sunlight,
11125 second is suitable for most photographs.
When indoors in a well-lit room, 1/60 second
should be sufficient to record your subject,
depending upon the  f ilm you are using. Final
determination of a shutter speed setting should
be made based on the action-stopping needs for
your picture, i.e. the more action, the faster the
shutter speed required.

DEPTH OF FIELD
When you focus on a specif ic subject, an area in
front of and behind that subject will appear
acceptably sharp in your picture. This area, or
zone, of acceptable sharpness is DEPTH OF
FIELD.
Depth of field is determined by the f-stop you
select and the distance from the subject in
focus to the film plane. As you get closer to
your subject, or as you open your lens (e.9.
from f 16 to f2.B), the depth of field becomes
shallower. By stopping your lens down (e.9.
from t2.8 to f 16), this depth or zone of
acceptable sharpness can be increased.
Another factor in depth of field is the focal TAKING THE PICTURE

provided by shorter focal length lenses is ideal
for "snapshooting" when there isn't time to

Shallow depth of field can be used to throw
distracting foregrounds and backgrounds out of
focus to add separation between a subject and
its surroundings.

REWINDING THE FILM
When you have finished taking all your pic-
tures, rewind the film back into its cassette as
follows:
1. Press the Rewind Release Button (11) be-
    side the speed dial.
2. Lift up the Film Rewind Crank (23) and
   turn it in the direction of the arrow until
  you feel the film tension lessen. This indi-
   cates the  f ilm has been completely rewound
    into the cassette.
3. Open the camera back by pulling up sharply
  on the Rewind Crank and remove the
   exposed cassette.
