     INSTRUCTIONS
  lor Operating the Diomatic
    Shutter with which this
      Kodak is Equipped
 A LL instructions in the accompanyingl1  manual are to be followed carefully, with
the exception of those for operating the shut-
ter, and the table for the use of the dia-
phragms, for which substitute the instruc-
tions in this leaflet.
  Over the lower seale on this shutter is a
movable slide, with divisions indicating four
degrees of light intensity: " Brilliant," " Cle&r,"ttGraytt      ttDull.t'       and
  Brilliant-intense sunshine. For use when
the sunshine is very clear and intense, and is
shining directly on the principal part of the
eubject.
  Clear-ordinary sunshine. For the &vera,ge
instantaneous exposure; also for intense sun-
shine when it is not shining directly on the
principal part of the subject.
  Gray-hazy or dull sunshine. Best judged
by the shadow cast by the sun which would
be called "half-shadow," or when only a faint
shadow is visible.
  Dull-sunnof visible; sky completely over-
cast with light clouds or slightly smokyatmosphere. With heavy clouds it  will be
necessary to make a longer exposure, turn-
ing the dial at the top of the shutter until       ((8""T" or       is under the indicatorA, depend-
ing on your judgment, then make a time or
"bulb" exposure.

 lnstantaneous and Retarded Exposures
  Important-Although an automatic ex-
posure of 1/10 second may be made, exposures
of this speed must be considered time ex-
posures so far as providing a tripod or other
firm support is concerned. The camera can-
not be held steadily enough in the hands for
exposures slower than ll25 second.
  First-Turn the dial at the top of the
shutter until the division representing the
time of instantaneous or retarded exposure
required is exactly below the indicator A.
  The shutter is marked: 10,25, 50 and 100.
These figures indicate fractional parts of a
second, thus: lll0, L125,1/50, and 1/100.

For ordinary outdoor work such as street
scenes, nearby views, etc., with.the subject in
the sunshine, use stop /. 11 and ll25 second.
  For open views, when the sunlight on the
subject is unusually strong and there are no
heavy shadows, such as views at the seashore
and on the water, use stop/.16 and l/5Osecond.
  For ordinary landscapes, in bright sunshine
with clear sky overhead, use stop /.16 and
U25 second.
  TVhen the sky is overeast with light clouds
or slightly smoky atmosphere, use 1.7.7 and
U25 second.
  As a general rule, 1/100 second should be
used only when making snapshots of moving
objects in bright sunlight and stop /.7.7 must
be used for all such pictures.
  Instantaneous Exposures should not be
made when there are'heavy clouds.
  Second-Move the slide B controlling the
diaphragm or stop openings to the proper
point depending on the time of exposure, in-
tensity of light and kind of subject. See in-
structions for the use of the diaphragms or
stops, on the last two pages of this leaflet.
  Norp-The slide over the lower scale willbe
a great help in determining the correct ex-
posure, necessary, with the various diaphragm
or stop openings, and under varying light con-
ditions, for the average subject. There are a
few exceptions to the rule, see tablefortheuse
of the diaphragms on the last two pages of this
leaflet.
  Third-Press the lever E to."set" the
shutter, ready for an exposure.
  Fourth-Press the push-pin of the cable
release D, or press the exposure lever C. This

 ma\es the eaposure. Hold the Kodak rigid, as
 a_ slight jar will blur the image. Exposures
 slower than ll25 second musl not be made
 when the Kodak is held in the hands.
  Avoid making too sharp a bend in the cable
 release or it may kink.
          Time Exposures
  First-Turn the dial at the top of the ehutter until the letter "T" (time)-is under the indicator A. This adjusts the shutter for
Time Exposures.
  Second-Move the slide B to f .7.7, 11, 16,
 22,_32 or 45, depending on the time of exposure
and nature of the subject. See instructione
 for the use of the diaphra,gms or stops, on the
next page of this leaflet, also, the table for
making Interior Time Exposures and the table
for Time Exposures Outdoors, given in the
 manual.
  Third-Press the lever E to "sel" thechutter.
  Fourth-Press the push-pin of the cablerelease D. This opelrs the shutter. .Time the
exposure by a watch. Again press the push-
pin. This closesthe shutter. The shutter may              -byalso b_9 opened     pressing the exposure
lever C and closed by a second pressuie, but
great care should be taken noi to jai the
eamera.
          "Bulb" Exposures
  For short time exposures, of about ten
eeconds or less, "Bulb" Exposures are recom-
mended.
  First-Turn the dial at the top of the shut-
ter until the letter "8"  (bulb)^is under theindicator A. This adjusts the shutter for
"Bulb" Exposures.

Second-Move the slide B to f .7.7,11, 16,
22,32 or 45, according to the time of exposure
and nature of the subject. See instructions
for the use of the diaphragms or stops, given
below, also, the table for making fnterior
Time Exposures, and the table for Time Ex-
posrrres Outdoors, given in the manual.
  Third-Press the lever E to "set" the
shutter.
  Fourth-Press the push-pin of the cable
release D or press the exposure lever Cto open the shutter and release it to close the
shutter. This makes the erposure. The shut-
ter will remain open as long as ttre push-pin'
or exposure lever is under pressure.
 Time and"Bulb" Expsures must not be
made with the Kodak held. in the hands.
  As a general rule, make exposures with the
cable release instead of the exposure lever, as
it is less likely to jar the camera.
             Important
  Do not oil any part of the shutter.
  In case of accident, return the Kodak to
your dealer or to us for repairs.
            Diaphragms
  The diaphragms, or stops as they are some-
times called, are the openings that regulate
the amount of light passing through the lens.
The openings are enlarged and reduced by
moving the slide B on the lower part of the
shutter.
  J.7.7-Fot instantaneous exposures, on
"Gray" or hazy days, use 1/25 second, and
when the light is "Clear" or "Brilliant" use
l/50 or 1/100 second repectively; also for
portraiture, see instructions in the manual.

www.butkus.us
  /.11-For all ordinary outdoor work, such
 as nearby landscapes showin.q little or no sky,
groups and street scenes, when the light on
 the subject is"Clear," use 1/25 second.
  /.16-For open views, when the sunlight
on the subject is unusuallg "Brilliant" and
 there are no heavy shadows, such as views at
 the seashore and on the water, use 1/50second;
for ordinary landscapes, in bright sunshine'with      clear sky overhead, use 1/25 second, also
for fnterior Time Exposures, the time for
which is.given in the manual.
   f .22-For instantaneous exposures of ex-
tremely distant landscapes, marine, snow
scenes and clouds, in bright sunlight, use
 1/25 second; for ordinary landscapes, street
6cenes, or nearby subjects when the light is
"Brilliant," use 1/10 secondl also for time ex-
 posures.
  f.32 and /.45-For time exposures out-of-doors on cloudy days, the time for which is
given in the dble in'the manual. For fn-
 ferior Time Exposures, see the manual.
The smaller the stop the sharper the picture.
 Total failure will be,the result if stops f .32 or
1.45 are used for instantaneous erposures.
  Norn-In all the instructions, the ex-
 posures given are calculated for hours from
2%hourA after sunrise until 2r/2hours before
sunset. If earlier or later the time required
 will be longer. For objects in the shadow,
under porches or under trees, no accurate
directions can be given; experience only can
 teach the proper exposure to give.
