5. Preparing for Picture Taking, Picture Taking
5.1. Camera Loading
Turn off the screw on the case bottom and remove the camera
from the case.
Raise two locking clips on the camera base plate and turn
them as far as they will go; move the cover along its grooves and
take it off the camera. Place the cassette with film in the seat and
put it on the cassette spool guide.
Pull the film end out of the cassette as long as to the camera
edge, insert it in the take-up spool slot. See that a sprocket tooth
would enter a perforation hole.
Insert the detachable cover into the camera guide grooves and
move it as far as it will go. Give the locking clips half a turn till
stop and then sink them into their recesses.
Set the shutter, press the release button. On setting the shutter the film moves by one frame. To
advance unexposed part of film to the film gate set and release the shutter two times.
Before releasing the shutter after the second setting set figure “0” of the exposure counter dial
against the index mark on the shutter setting lever.
If the film is wound tightly in the cassette, the film rewind knob will rotate when the shutter is
being set. Should the film be wound loose in the cassette, the knob will fail to rotate at the initial
frames. Now you can put the camera into its case. Do not forget to tighten up the tripod screw in the
case bottom.
5.2. Shutter Speed Setting
Shutter speeds may be set only with the shutter set. Pull up the
shutter speed dial and turn it till a required shutter speed value is
set against the index mark. Release the dial in such a way that it
would be fixed without pressing.
Figures on the shutter speed dial denote corresponding
fractions of a second and letter “B” — hand-controlled shutter
speed.
To obtain an exposure longer than 1 second, set the dial index
mark against letter “B”. In this case the shutter stays open till the
release button is pressed.
To obtain a still longer exposure the release button can be fixed in this position by turning it
counterclockwise as far as it will go. The exposing over, return the button into the initial position.
To avoid mechanism disengaging, do not rotate the button without need.
It should be remembered that to set the shutter speeds of 1, 1/2, 1/4, 1/8, 1/15, 1/60 of a second, an
additional effort is required to wind an additional delayed-action mechanism spring. When the shutter
speed dial is being reset for a shorter exposure time, the delayed-action mechanism is heard operating.
Besides it, when shutter speeds of 1; 1/2; 1/4; 1/8; 1/15 and l/60th of a second are used, the shutter
speed dial is fixed somewhat higher as compared to other shutter speed settings.
5.3. Lens Aperture Setting
Match a selected aperture value with the index mark (dot) by rotating the ring with an aperture scale
of JUPITER-8 lens (or the ring with the index mark of INDUSTAR-50 lens).
For convenience each of the indicated lenses has two equivalent aperture scales and two
corresponding index marks.
5.4. Focusing
Objects having sharp contours should be selected for focusing.
Watching through the range-viewfinder eyepiece, turn the diopter adjustment lever to obtain the
sharpest image of an object in the eyepiece.
