4.  Light value deciding:
    The light value calculator is a great help to the exposureproblem. To
make useof  it,  first adjust film speeddisc (2)  to the correct ASA or DIN
index nurnber to the same as the speedof the film  in use. Then chooseone
of the weather legends,according to the weather condition found on  light
value ring (3), turn this ring until the pointer of this weatherlegend points
at one of the 5 picture taking situations(fig.8).  The red arrorr on the
disc will then point at a number (from 4 fo 17) which is the light value
index required.  (This figure may be used as a starting point in experiments
when subjectbrightness,etc., call for further adjustments.)
     Similar light value numbersare found on shutter speed ring ( l5).   For
correct exposure,set light value lever (5)  located besidesthe shutter speed
ring at the same figure as found by the light value calculator. This can be
done by lifting the lever slightly up and placing it in position (fig.9).  Care
must be taken not to handle it roughly, otherwise it may be damiged.  Since
this lever has a limited travelling space, sometimesit is necessaryto turn the
shutter speedring as well in order to fix up the light value combination.

    Once the correct  light  value has been set, the shutter speed and  dia
phragm  are coupled.  A  shift  in  shutter speed results  in a corresponding
change  in  diaphragm  opening.  The  effective  exposure  of  each combi-
nation  is virtually  the same.  When  the  shutter speed happens to stop
at  "8",     it means a 2 second exposure is required.
    There are  limitations  to both sides where  the light value lever will
stop removing and slipping.   This range represents the limit of light value
combination device, only within  which  adjustment  is possible.
    One may  prefer  to choose one's own  shutter speed and  diaphargm.
This can be done by  rotating the shutter speed ring  until the red spot on
it comes to the speed desired and  lifting  the light  value lever a little  bit up
and  let diaphragm pointer  (12)  set against the stop chosen (fig. 10).
      In case available  light  being  too dark as to be beyond the light  value
figures  the exposure must be longer then 2 seconds.  The correct exposure      E 10  (Fis.1o)can only be obtained by experience or with  the help of an cxposure meter.

5.  Viewing  and   f ocuring:

    The design of the viewing  system of  this camera  is a com-
bined distance meter and   view-finder.   Lcxrking  through  the    E 11 (Fig.tt)   E 12 (Fig.12)
eye-piece of  finder  (20,  fig.4),  an image as  it  will be recorded
in  the picture  will  be seen.  A yellow  square  is found  in  the
centre, in which  the outline of the object  will appear as one or
slightly  apart.  The presence c.,f a double image indicates "out
of  focus"  (fig.  12)  wirile a single cr-.'ntourmeans correct focusing
 ( f i g . 1 1 ) .

     Vertical  lines, such as the side of a  building,  a
pole a  tree. etc. are  ideal  for  accurate  tocusing.
F-or  pr<-rtraiture, the contour  of  the face  may  be
taken  as guidance.

    The camera must be held as steadily as possible during exposure.  Exposure longer than 1,/30 second calls for
the help of a tripod or some other means to act as support, so as to avoid blurred pictures,
     Fig. 13 shows how to focus properly  (with  the left hand holdin   the camera front and
turning focusing ring (4)  with the thumb at the same time).
     Fig. 14 shows the way of holding the camera while taking horizontal pictures of 6 X 4.5
cm slze.
     In the view-finder, two white bright lines are visible. They mark out the margins for
taking 16 pictures.
    Avoid  incident light  falling  directly on the lens during exposure lest a blurred negative
may occur.

 6. Depth  o[  field:

 -     Pictures obtained by  correct focusing will  show acceptabte sharp image not onty  of  objects focused on
 but also of  objects nearer or  further away  from   it.   Thi,   ,orr.  is           tie  depth of  fiekl                                                                                     "all"d
    Depth of  ficld varies with  the lens opening an<I the fcused  tlistance. The larger tle   lj  number  used,
the grealer the <lepth of  field.  lhpth  of  fiekl also irrcreasesas the distarrce fnrm  the camera to  the object
increased.
    The depth of  field  for  any lens opening an<l distance may be reatl off  from  tlistance scale ring (?,  Fis.
l5).   For  example,  for  a  distance of 3 meters and an opening of   f:  8, the depth  of  field comes from  a
little  over 2 meters to about 5 meters from  the camera, as shown by depth of  field scale (6) on the front.
The  two  figures  "8"  on  both sides to  the red  triangle mark  out  the  zone, anything  within  which  wilt
appear sharp.

    Stop the opening at   f:  16, the depth  of  field   will  be greater,  i.e. from  approximately  2 meters to 7
meters from  the camera.  Stop  at  f:  4, the depth of  field  will  be reduced to around 3 meters only,
                                           Taking advantage of  the above theory, when  light  condition
                                         permits but time of focusing is lacking; just set the distance at  l0
                                      meters with  the lens opening between f : 8 and  f:   I l,  then every
                                            thing from 5 meters to  infinity   will  look sharp.

                                       7 . Shutter  and Selftimcr  tensioning:
                                       The  shutter should only  be tensioned before every exposure
                                                                     It  is done by pushing shutter tensioning lever ( I I ) to the direction
                                      as shown by the arrow  in  fig, 16 until  it clicks.
