 fast instantaneous exposures, also revolve disc C until the
 white line stands opposite R,

  taining four apertures as follows: Full openings for time or
  slow instantaneous, 2", L" and 14" apertures for instantaneous
  exposures. Any of these apertures may be brought into posi-
  tion for exposure by turning key A proceeding from the large,
  or full, opening to the smaller apertures; or the curtain may
 be lowered from the smaller to the larger aperture by drawing
 back on lever M located directly back of the winding key.

    A safety lock prevents the curtain from being re-wound before
       the mirror is set when mechanism is set for instantaneous ex-
       posures, this prevents fogging the plate or film while dark
        slide is withdrawn, making it necessary to set the mirror be-
        fore rewinding the shutter.
    REGULATING Turn large milled head B, located on right                          side near bottom at back of camera, to the    SHUTTER
                                                                      ap-    SPEEDS     right unti] the desired tension number                        pears at G. The numbers run from 1 to 6,
       the highest number indicating the greatest speed. To lower
        tension, push escapement button P, directly below winding but-
       ton up and down until the tension is lowered to the desired
       number.
    MAKING THE To make an instantaneous exposure when    EXPOSURES the object to be photographed is focused                       sharply upon the focusing screen, press
      downward on lever E, near the front on left-hand side of cam-
        era, releasing the mirror, which travels up out of the cone of
        light, automatically releasing the shutter. As the action of
        these is simultaneous, the object, although moving broadside to
$i      camera, can be located perfectly in the center of the plate or
         film.tr

    SLOW INSTAN- Slow instantaneous exposures may be
                     made by winding curtain until T shows on    TANEOUS EX.                          aperture index at F, and turning disc C so   POSURES                           that the white line stands opposite letter
        S, which permits the full curtain aperture, 8", to pass over the

recording field, giving exposures as indicated in fourth column                -indicatedon speed plate,         as the 8" curtain aperture column.
Howbver, these slow instantaneous exposures may be increased
by winding curtain up until the 2" registers at letter F, which
will permit ttre 2" and 8" curtain apertures to pass the record-
ing plane, giving a 25r( increased exposure to that shown inthe fourth or 8" curtain aperture column. It is not recom-
mended that the entire number of curtain apertures be allowed
to pass the recording plane.
                 Depress' disc D and revolve until letter TTIMEIXF-OSURES stands opposite the white mark on lever H,               turn disc C until the white line stands oppo-
site letter R. Wind the curtain until T shows at the curtain
aperture F. Set the mirror in the usual nlanner. After focus-
ing, relea-"e the mirror, which travels up out of the cone of
light. Begin the exposure by pressing lever N[ and terminate
the exposure by a second pressure on lever M.
RISII\G The swinging, rising and falling front is controlled                                     upper corner ofFRONf by milled head J at right-hand         front. Being operated by beveled gear and quick
thread, it locks automatically at any desired point, but should
be centered as indicated by the line on right-hand side before
closing front of camera.
REVOLVING The revolving back may be released for turn-
nlC[(         ing to a horizontal, vertical or intermediate                 position by pressing inward on small button
directly below shutter-winding mechanism.
