Tperation of the Premo Film Pack
For the first exposure gently pull out tab marked
" Safety Cover," holding the remaining tabs und'er
the finger and thumb of the other hand to prevent
the possibility of putling out more than one tab at
a time. (Fig. 6.)
When the red cross line appears' tear off from left

straight edge.
The first film is now presented for exposure'
Having made the exposure, pull out in a sim-
ilar manner the black paper tab marked "No' 1"
and tear off. Film No' 2 is now presented for
exposure. RePeat the oPeration
of pulling out and tearing off the
black paper tabs one at a time, as

PART II
IVlaking the Exposures
Before making an exposure with the premo No.
\2, either tirne or instantcneous, be sure of four
things:
Frnsr - That the shutter is adjusted
properly.
(For time, instantan-
eous or bulb exposures
as desired).
SncoND 1'hat - the diaphragm stop
is set at the proper
opening.
Tnrnn-That the
camera is focused.
Founur-That an
B unexposed film is in
Shutter as is used on the premo position. No. 12 when fitted the with R. R. Lens Norn-Exposures are
made by pressing push-
pin at end of cable release D or pushing d.own on release c.
Avoid making too sharp a bend in the cable
release, &s by doing so it will be liable to kink.
SECr/ON I
Operating the Shutter
Perfect familiarity with the shutter is essential to
successful picture taking with any camera. 1'he
following directions should therefore, be carefully
read and the shutter operated several times before
attempting exposures.

In case of accident, return shutter to your dealer
or to us for repairs. As a general rule, make expo-
Sures with the cable release irrstead of release C, as
the cable release is less liable to jar the camera.

Press the concealed buttcn, &s shown in Fig. 1,
and push down the bed of the camera to the limit

'lhe Carnera is now in focus for objects at a distance
of 100 feet or more from the lens.
In order to focus on objects nearer to the lens thaR

ing scale ancl then push the catch forward until the

indicator is exactly over the figure indicating the
distance desired.
NoT e: The index plate is scaled both by feet and by meters
and care should be taken not to confound. them,
Except when photographing at a distance of 15
feet or less, it is not necessary to estimate the dis-
tance with any more than approximate accuracy;
for instance if the focus is set at 25 feet (the usual
distance for ordinary street work) the sharpest part
of the picture will be the objects at that distance
from the camera, but everything from 15 to 35 feet
will be in good focus. For general street work the
focus may be kept at 25 feet, but where theprincipal
object is nearer or farther away, the focus should be
changed accordingly. The index plate is divided
for 6, 10, 15, 25, 50 and 100 feet. Everything be-
yond 100 feet is in the 100 feet focus. Nothing
nearer than 6 feet can be focused without using the
portrait attachment. See page 24.
Note : Before closing the camera, make sure that the catch on focusing scale is in the notch at the 100 ft. point, as unless this is done, it wiil be impossible to close the Camera properly.
How to Use the Premo No. 12 as a Fixed
Focus Camera
Set focus at 25 f.eet.
Use speed of 1-25 of a second.
Set diaphragm midway between 8 and 16 or F.11
and 16.
By following the above suggestions this camera
can be used as a fixed focus instrument with the
additional advantage of being instantly convertible
to a focusing camera when conditions call for it.View original page 15Page 16 · Read text
www.butkus.us
It must be remembered however, that wheu using
this camera as a fixed focus type, it is n"c"ssor]
that the subject be in briiliant slntigfrt, in order to obtain a fully timed exposure.
Explanation
A lens is often spoken of erroneously as having a fixed focus.
There is no such thing as a universal or fixed focus
Iens, but in certain Sft-lensesxa/ and smaller ( equipped with short""*"r.r,focus ) the lens is
unmovable, i. e., set at a distance that is a compro-
mise, as to its focus, between far and ouu, poiota.
A camera with a lens so focused, used in combina-
tion with a relatively small stop, is designated a " universal or fired focus instrument. gr+fur4j
Use Stop No. 8 or.F. 11
For all ordinary out-door work when the sun is
bright use stop No. g or F. 11. If a smaller stop be
used, the light will be so much reduced that it will
not sufficiently impress the image on the film and failure will result.
In views on the water when the sunlight is unus_
ually slrong and there are no heavy shadows, dia_
phragm No. 16 may be used.
If a smaller stop opening than No. 16 be used for
snap shots absolute failure zuitl result.
Locate the Image
Aim the camera at the object to be photographed
and locate the image in the finder. For a v".ticat
picture with the premo No. 12 hold the camera as

show a facsimile of the picture as it rn'ill appear, but
on reduced scale.
Any object that does not show in the fincler will
not show in the picture.
It will be noticed that on the top of the finder are
trvo corrusatecl projections by means of which the
top of the finder may be revolved. When a vertical
picture is to be taken, see that the indicator on lower
part of the top of finder is over the letter V and
when the finder is reversed as when taking a hori-
zontal picture the indicator must be over the letter H.

To Make a Portrait
Place the sitter in a chair partly facing the Camera
(which should be located slightly higher than an
ordinary table) and turn the face slightly towards
the instrument, having the eyes centered on an j
dobject at the same level with the lens. ,li
Center the image in the finder. For a three-quar- .tI

,'* Kodak Portrait Attachment $ The attachment is simply an extra lens slipped
on over the regular lens and in no way affects the
operation of the lens except to change the focus.
By means of the Portrait Attachment large head
andshoulders portraits of various sizes may be ob'
tained. With the Atttachment in position and the
Camera set:
At 6 feet focus, the subject should be placed
exactly 2 feet,8 inches, from the lens.

The above is ealculated for the same hours as
mentioned above and for objects in the open air.
For other hours or for objects in the shadow, under
porches or under trees, no accurate directions can
be given; experience only can teach the proper ex-
posure to give.
Time exposures cannot be made while the Camera
is held in the hand. Always place it upon some
firm support, such as a tripod, chair or table.
For exceed.ingly "short time" exposures, as above
described use the "bulb exposure." See pages 11
and 13.
Diaphragms
If using the model fitted with the DOUBLE LENS, (Rapid
Rectillnear) the stops should be used as follows:
No. 4-For instantaneous exposures on slightly cloudy
days.
No. 8-For all ordinary instantaneous ezposures when the sun
shines.
No. 16-For instantaneous exposures when the sunlight is
unusually strong and there are no heavy shadows, such as in
views on the seashore or on the water; also for interior time
exposures, the time for.which is given in the table on page 23.
Nos. 32 and 64-For interiors. .Neuer for instantaneous erlo-
sures. For time exposures outdoors in cloudy weather. The
time required for time exposures on cloudy days with smallest
stop will range from l-5 second to 5 seconds, according to the
light. The smaller the stop the sharper the picture.View original page 24From the M. Butkus archive. Original publisher and archive notices are retained.
