BATTERY FOR THE CdS EXPOSURE METER The built-in CdS'exposure meter is powered with a 1.3 volt mercury battery (Mallory RM 675R, National M'1C, Toshiba TH-KC or equivalent). The battery compartment is located on the left-hand front side of the top cover. The exposure meter isswitched on bya stroke of the,film advance lever. When the exposure meter needle does not respond to a change of light conditions, the battery has become exhausted and must be replaced. Unscrew the battery compartment cover with your finger tips .ld insert a new battery with the plus (+) upward, facing the battery compartment cover, into the battery compartment. -7 -View original page 9

things happen simu ltaneouslY:
1. The battery switch is turned on and the exposure

3. The film counter is advanced.
4. The shutter is cocked.
After the shutter is released, the battery circuit is shut
off and unnecessary battery drain is avoided:

FILM SPEED (ASA OR DIN} SETTING
After the film has been loaded, be sure to set the ASA or DIN film
speed index specified for the film in use on the film speed scale. This
adjusts the exposure meter for the film being used and an essential
step in getting properly exposed pictures.
To set the film speed, raise the external ring of shutter speed dial and
turn to align the reading equivalent to speed of the film in use with
the index mark. Do not set in between click-stops. lf the reading
does not align correctlrT, the ring will never drop down. The black
numbers represent ASA values and range from ASA 25 to 800, and
the red numbers represent DIN values ranging from DIN 15 to 30.
Read the instructions supplied with the film and set the correct film
speed index number. lf the number of the film speed corresponding
to that of your film is not available on the film speed scale, use the
closest number and never set betweerl two settings. For convenience,
the positions for intermediate film speeds are shown only by dots.

SHUTTER SPEED DIAL
Your camera shutter has a range of speeds covering sufficiently all the ordinary
picture situations. lt has the settings of : 1/1OOO,1/500, 11250,11125,1160,1130,
1115, 1/8,114,112 and 1 second and Bulb. When the Bulb setting is used, the
shutter stays open as long as the shutter button is being depressed (for time
exposure). The settings are represented onthe shutter speed dial located right-hand
on top of the camera body. For convenience, only the lower half of the numbers(250
for 1 /250, etc.l and B (for Bulb) are etched on the black wheel. The shutter
speed is set by lining up the appropr'iate number or B with the black line on
'between the top cover. Do not set the shutter speed two click-stops.
The shutter speed can be selected either before or after the shutter has been
cocked.
For indoor photography, it is recommended to set the shutter at 1/30 or 116O;
for outdoor photography, at 11125 or 1125O; and for action photography such as
in sports or snap shots it is important to use faster speeds of 1125O,11500 or
" 1/1OOO to avoid blurring.
The number "15" for 1/15 second is larger than others and painted in fluores-
cent. When using the shutter speeds slow.er than.1/15 second, it is recommend-
ed to use a tripod and a cable release equipment so as to avoid camera shake,

NOTE
1 The B (bulb) setting is not usable in the Electric Eye photo-
graphy. Switch the diaphragm to the manual operation and
set the diaphragm by turning the diaphragm scale.
2 The stopped-down light measuring is applicable to the 55mm
standard Electric Eye lens, but not to other interchangeable
Electric Eye lenses.
EXPOSURE WARNING MARKS
In the viewfinder there is a diaphragm scale and
on each end of the scale you will notice the red zone.
The red mark below the f/16 is an over-exposure
warning mark, and the one above the tl 1.4 (or
an f /1.7 lens) is the one above the f /2 for
under-exposure warning mark.
R E {1) OVER-EXPOSU
When the exposure meter needle swings down to the
over-exposure warning mark, it shows "over-
exposure". Set the shutter at a faster speed or use an
appropriate filter to absorb the amount of light. (For
the proper filter, see Page 34.)View original page 15Page 17 · Read text

VIEWFINDER AND FOCUSING
PETRI FA-1has the original PETRI Micromatic Focusing system
for fast and accurate focusing. The precision focusing elements in
the viewfinder consist of a group of more than 800 micro-prisms as
shown in the center of the picture.
As you look through the micro-prism area @ in the viewfinder,
vou can see the subject clearly, ONLY when it is correctly
focused. Rotating the focusing ring you will notice the appearance
of something like a mesh of a net in the center of the viewfinder.
This reticulation is caused by the flickering of reflected light @ @ c
entering the camera lens. When the subject is correctly focused the
flickering grid fades away from the micro-prism area. In the
is second inner circle @ is the plain glass area where the subject
always seen sharp and clear, even when the lens is out of focus.
When the lens is correctly focused the image in the micro-prism
area will be as sharp and clear: as that seen in the surrounding circle
@.

DEPTH OF FIELD
A lens that can be focused lets you accentuate the important image in a
picture, while it can de-emphasize irrelevant objects in front of and behind
the main subject by throwing them out of focus. This involves what is
known as "Depth of Field". The smaller the aperture is the more the
depth-of-f ield i ncreases.
HOW TO READ THE. DEPTH OF FIELD
The scale is engraved on the lens barrel of your camera and indicated in
black lines spreading out both sides of the index marker at the center.
Simply focus the lens in the normal way, and each pair of black lines
which points to the diaphragm scale indicates the depth-of-field zone
corresponding to the diaphragm you set.
For example, the depth-of-field zone for the standard 55mm lens is
indicated as follows: When the focusing distance is 8 feet and the f/l1
is selected, one of black lines at f/11 points to 6 feet, the nearest point
still in focus, and the other points to approximately 12 feet on the
+ other side, being the furthest distance in focus.

HOW TO HOLD YOUR PETRI FA-1 CAMERA
The format of your picture is determined by the position in which you
hold the camera. Holding the widest part in a horizontal position will
result in a horizontal format. Holding the widest part in a vertical
position will result in a verticat format. Blurring in a picture often is
caused by camera shake at the moment of exposure. Practice holding
the camera and releasing the shutter so you can take pictures without
jarring or shaking it.
Use the following three simple.rules for taking a pictune to aroid
camera movement:
1. Before releasing the shutter, take a deep breath and hold it until
after the picture has been taken.
2. While taking the picture, hold the camera firmly with both
hands and press the back against your face and forehead as
firmly as possible
3. Squeeze the shutter release button, do not prod or tap it.
Practice squeezing until you can release the shutter without the
slightest quiver.View original page 25Page 26 · Read text
