BATTERYFOR THE CdS EXPOSUREMETER
Thebuilt-inCdSexposuremeteris poweredwith a 1.3voltmercury
battery of the Mallory PX- 625 or equivalent type. The battery
compartment is located on the left-hand front side of the top
cover. The exposure meter is switched on by a 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.
U nscrew the battery compartment cover with your f inger ti ps
a n d i ns ert a n e w b a t t e ry with the plus (+) upward, fa c i n g t h e
battery compartment cover, into the battery compartment.

SHUTTERSPEEDDIAL Your camera shutter has a range of speeds covering sufficiently all the ordinary picturesituations.lt has the settings of:1/1O00, 1i5O0, 1/25O, 1/125,1/60,1'3O,1/15,1/8,1/4,1/2and 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 representedon the shutter speed dial located right-hand on top of the camera body. For convenience, only the lower half of the numbers(250 for 1/25O' etc.)and B (for Bulb) are etched on the black wheel. The shutter speed is set by lining up the www.butkus.us appropriate number or B with the black line on the base of the accessory shoe.Do not set the shutter speed between two click-stops.The shutter speed can be selectedeither before or after the shutter has been cocked. For indoor photography, it is recommendedto set the shutter at 1/3O or 1/60; for outdoor photography,at 1 /125 or 1/25O: and for action pho- tography such as in sports or snap shots it is important to use f aster speedsof 1/5O0 or 1/1000 to avoid blurring' The number "15"for 1/15 second is larger than others and painted in blue. When using the shutterspeeds slowerthan 1''l 5 second,it is recom- mendedto use a tripod and a cablereleaseequipmentSo as to avoidcamera shake. t lView original page 13

T H R O U G H . T H E - L E N S S Y S T E M
Your Petri TTL camera has a built-in, through-the-lens
exposure control system utilizing the most sensitive
measuring devices available in ordinary photography.
Two'cadmium sulfide (cds) cells,located on each side of
the pentaprism base, measure the average brightness
of the image entering the lens and reflected to the
CdS Cell viewf inder. This through-the-lens measurement is trans-
lated into an accurate exposure indication registered by
the needle in the viewfinder.The readings are accurate

DEPTH OF F IELDT he de Pth of

what is known as " Depth of Field". The smaller the aperture is
the more the depth-of-field increases.
HOW TO READ THE DEPTH OF FIELD

indicated in black lines spreading out both sidesof the index marker

FLASH PHOTOGRAPHY
When the exposure meter needle in the vievrrfind-
er stays below the circle (see page t7 )and even a
larger aperture opening and slower shutter speed
can never make it come up into the circle it
s h o w s t h a t t h e lig h t in g condition is too poor
and that you must switch to f lash photog raphy.
Photography with flash noq only extends your
picture possibilities g reatly but adds excitement
and d rama to your pictures. The use of f lash
equipment with your camera is relatively simple
because it has built-in synchronization. lt is equip-
ped with X synchronization. Therefore, both
electronic flash and ordinary single-exposure
flashbulbs can be used.
