No. 1-A Folding Hawk-Eye
             Model No. I
       .        For Pictures 2% x 4%
  Before loading or attempting to take any pictures with
the Hawk-Eye read the follorving directions carefully
and become thoroughly familiar with the instrument,
taking special care to learn the construction of the
shutter; work it for both time and instantaneous ex-
posures, before threading up the film.
 A most important thing to be remembered is that no
white light (including gas or lamp light) should reach
the film for a fractional part of a second until it has
been developed and fixed. Therefore extreme care must
be used to keep the black paper wound tightly on the
spool so as to protect the film while loading and unload-
ing the Hawk-Eye. It is best to select some place where
the light is not too bright to insure safety.
            To Load
  Before  loa,dingo try  the  shutter  a,nd see
th.a,t it 'works properly.
  The film for the No. r-A Folditrg Hawk-Eye, X'fodel
No. r, is knorvu as'No. r-A F. P. K. cartridge, size
ztl x 4r/+, and is put np in light-proof 'cartridges so the
camera can be loaded and uuloaded in daylight. It  is
best that the operation be performed in subdued light,
not in bright sunlight. After the seal is brokeir,  it
                            3
                       www.butkus.us

must be borne in mind that care must be taken to keep
 the black paper tight so no light can reach the film.
  To insure against all dangers, it is advisable to select a
 place where the light is not strong, as this work should
 never be performed in the glare of bright sunlight.
  Hold the camera in both hands as illustrated in Fig.
 r;  first press with the forefinger of the left hand on thl
 little knob D and at the same time with the forefinger
 of the right hand push the little knob E toward ih.
 u'inding key which releases the back cover.





                        Frc. r

  Pull out the spool centers at each end of the empty
chamber about r% inch until the inside ends are flusir
with inside of spool chamber; then place the film cart-
ridge into position (the word "Top" on a Kodak spool
should be at the bottom of the camera), using care that
the centers when pushed back engage in the holes in
the ends of the spool.
  The film cartridge should be placed in the camera so
                        4\

that the paper ullwinds  f rorn the outside or off the top,
as it were. Break the seal and pass the black paper
over the rolls at back of camera and thread into the
slot in the winding re el. Tttrn the key to secure.
  Be careful that it is started straight, for should one
edge bear aga.inst the flange harder thau the other, it
will not wind evenly and r,vill cause trouble. See that it
is perfectly centered. After the film is secured, replace
the back cover by hooking it to the end of the camera
opposite the handle ( see trig. 2) , using care that the
end A is correctly engaged at the point B before the
cover is pressed dowtr to engage the catch C, but the
cover will not lock until thc krrob D, illustrated in Fig.
r, is pressed do'uvn, at the same time pressing o11 the
back cover to bring it into place and make the lock
engage.

  Throughout the  f oregoing  f rom the tirne the seal is
broken until the camera is closed, see that the black
paper is wound tightly on the spool.  I f the paper is
allowed to loosen the film r,vill be  f ogged.
  Turn the winding key slowly until the figure r ap-
pears opposite the red wirldow, r,vhich signifies that the
film is in position for the first exposure.           \

Shutter Used on Model No. I
  The disc at the ltottom of the shutter inclicates the
 opqning of the iris diaphragm, according to the uniform
 system. The graduated disc at the top o f the shutter
 indicates different methods of makirrg exposures as
 desired.             3'T"  Opposite     time exposure of any duration is ob-
tained by.pressing th.. bulb to open the shutter, and
 pressing  it again to'close  it.





  Bulb exposures are obtained by piacing the pointer
opp.osite "B," pressirrg the bulb, when th; shutter re-
mains open as'long as pressllre is applied to the bulb.
   Itrstantaneorls exposures are made by placing the
pointer upon #,utu or r*o ?S desired.
  This shutter r,vorks arltoruaticall-v and is always set
and ready  f or making an exposure.
            Stops or Diaphragms
 - The stop or diaphragm is the opening which regulatesthe amour-rt of iight passing through the lens.
  The opening for the lens aperture can be reduced or
enlarged in accordance with the strength of light rvhen
making an exposrlre.
  Under ordinarl'conditions the B opening should be

   Instantaneous exposures,_,better known as,,snap                    -]J

  When ready for making the exposure hold the camera

                  Time Exposures
           In making time exposures some juclgmerrt must be

           FIash Light Exposures
. In making flash light exposures.with the Hawk-Eye itis not necessary to procure a flash lamp, or any appar-
                            IO

atus, as the Eastman flash sheets are all that is required
           and. they are. supplied for z5 cents per package con-
           talnlng materlal tof slx exposures.
               _ Many interiors can be photographed by this process
           that would be very difficult to photograph during the
         day owing to lack of light, or windows so located that
                it is impossible to darken them sufficiently.
         The camera should be placed on a tripod, table or
         some other secure support. Pir-r the flash sheet by one
          corner to a piece of white cardboard, which will act as
       a reflector, and which has previously beerl fixed in a
           perpendicular position. Place this about two feet be
           hind, and two to three feet to one side of the camera,
          with an extra piece of cardboard under the flash sheei
          to prevent sparks from falling and doing damage.
         Wh.g everything is in readiness locate the object in           the finder and open the shutter the same as when mak-
          ing time exposures, using the largest diaphragm. Ignite
          the lower corner of the flash sheet. which rvill burn
           brightly, and make the exposure; theu ciose the shnt-
            ter and wind the film to the next rrumber which appears
          to view through the red window
         One sheet is sufficient for exposure ',vith subiect  tell           feet away, in an ordinary room with light wails; two
           sheets when the subject is fifteen feet away; three sheets
        when subject is fifteen feet away, with dark walls and
           hangings.
          lVhen one or more sheets are used thev should be
         pinned to the cardboard, one over-lappin! the other

          by adding a small quantity of a ten per cent. solution of
          Bromide of Potassium; but should the Bromide be used
           the 4eveloper is ruined for other negatives, unless they           are known to be over-exposed.
  I        UNDER-DEVELOPMENT.   An  under-developed           negative is very thin and full of-  detail; the difference
          can readily be seen from one under-exposed.
         An under-developed negative can be improved to quite
         an extent by intensif)'ing as follows: Place in a solu-            tion of   tl  ot. Bichloride of Nlercury,                               ,l  ot. Bromide of Potassium,
                 16 ozs. Water.
            Let the negative remain until it evenly whitens, then
         wash and apply a solution of t oz. Sulphite Soda to r
           oz. Water. The negative will then darken, when it
           should be thoroughly u'ashed and placed to dry.
         OVER-DEVELOPI,IENT is caused by allorving the
            negative to remain in the developer longer than it should.
        An over-developed negative will appear very strong
         and intense, and requires a lorrg time to print.
          For reducing use the following formula:
              No. r   ,l ot.Red Prussiate of Potash,
                       ro ozs. \\,'ater.
               No. z   tl  or. I{yposulphite of Soda,
                       ro ozs. Water.
             X{ix Nos. r and z, and allow the negative to remain
           in the above solution until sufficiently reduced. Wash
         and place to dry.
        FOGGED NEGATIVES are caused by leakage of
           the dark-room, or by holding the negative too long in
          the ruby, light. This causes the film to darken soon
            after placing in the developer.
         AIR BUBBLES beneath the film while developing
         or fixing cause spots, and streaks are procluced by
           allowing a part of the material to remain uncovered
           in some of the solutions.

           image sufficiently upon it.. The progress of the printilg
          can be examined from time to time by removing the
           frame from the strong light and openingone-half oJ the
           hinged back, keeping the other haff fast-ened to hold the

Printing on Developing-Out Paper

With Welsbach light .or daylight it is trecessary to re-

  Place the paper in an ordir-rary printing frame, in the
same malrller as when using printing-out paper, having
the emulsion side of the paper toward the dull side of
