Lighting of the upper diode indicates overexposure and of the lower one --
underexposure. Turn the aperture setting ring 32 and the shutter speed dial 17 till
the moment when both of the diodes are lighting. It indicates the best possible
combination of the shutter speed and aperture providing for correct exposure.
However, if you fail to obtain simultaneous blinking of both of the diodes, and
changing the shutter speed and aperture values over between the two
neighbouring ones results in switching the lighting from one diode to the other,
you may select one of these values. In such a case the exposure will be still
acceptably correct.
2. Exposure setting in cameras with three-diode indication
Lighting of the upper (red) diode indicates over-exposure and of the lower (red)
one -- under-exposure. Turn the aperture setting ring 32 and shutter speed dial
17 till the moment when the middle (green) diode is lighting continuously. It
indicates the best possible combination of the shutter speed and aperture
providing for correct exposure. However, if you fail to obtain continuous blinking
of the middle (green) diode, and changing the shutter speed and aperture values
over between the two neighbouring ones results in switching the lighting from
one red diode to the other red one, you may select one of these values. In such a
case the exposure will be still acceptably correct.
PICTURE TAKING
Having prepared the camera for picture taking, cock the shutter, make sure of
correct focusing, framing and exposure setting and smoothly press the release
button to take a picture.
BEAR IN MIND that sharp pressure on the release button results in camera
shaking at the moment of exposure and thus in blurring of the picture.
When taking pictures see to it that index marks on the release button and the
camera top plate (between "T" and "V") should be lined up.
To take a picture with long exposure mount the camera on a tripod, set the
shutter speed dial 17 at "B", slightly press release button 5 (the shutter should be
set beforehand in the "ready to fire" position) and turn it counter-clockwise as far
as it will go ("T" position).
The exposure over, return the button to its normal (middle) position and release
it. As a result the shutter will close.
CAMERA UNLOADING
When the exposure counter shows figure 36, rewind the film into the cassette. To
do this:
- release the shutter, pressing release button 5;
- press bush 6 downwards as far as it will go;
- flip open crank 12 and rotate it in the arrow direction until the film leaves the
take-up spool. Try and rotate the crank smoothly, without jerks, and not too fast
to avoid traces of static electricity on film;
- pull film rewind knob 11 all the way out, open the back door and remove the
cassette;
