NOTICE.
The instructions given herewith should be
carefully read, and the instrument should be
repeatedly worked, until the operator is familiar
with its manipulation, before any attempt is
made to take pictures. The factthat either Dry
Plates or Film may be ruined by being carelessly
exposed to the light in loading or in the faulty
manipulation of the instrument cannot be too
strongly emphasized. Throughout all opera'
tions, care and attention to the instructions
should be exercised.
THE STAR PREMO.
In size, weight and simplicity of tperation. the
Star Premo is unequalled It may be used as
a plate camera, with the regttlar back and doubie
plate holder or it may be used as a daylight-loading
film camera with the film adapter and the Premo Film
Pack. In either case it means perfect photography.
When used as daylight-loading film camera. it
lpossesses some distinct advantages, which appeal
at once to the operator. The camera may be
focused at will on the scale or on the ground glass
afler each picture ; each exposure is on an individ-
ual film, and may be deveioped like a dry plate
Again, the film pack is a most easily manipulated
device.View original page 4Page 5 · Read text
DEFINITION OF PARTS OF THE STAR
PREMO.
The Box of the camera is the case or shell en-
closing the picture-making mechanism. The Bed
of the camera is that part of the box which falls
into a horizontal position when the camera is
opened. The ulew f nder is an adju3tment on the
bed of the camera for accurately locating the view.
As the view appears in the finder, so it will
^ppear in the f inished piclure. The siidmg fron I is operated
by the thumb screw adjustment at the side of the
lens. It is used to regulate the amount of sky or
foreground desired. The drau1 is the length of the
bellows with which the camera is equipped. The
ground g/ass is the square glass ground on one side
and fitted to the rear of rhe camera. it is exposed
to view by opening the door at the baik. Th'e
image produced by the lens is plainiy discernible
by looking upon the glass.
When a tripod is used. correct focus is easily
obtained by the use of the ground glass. The lens
is the eye of the camera, It sees the picture and I.{
permits the same to be accurately registered upon
r ,i the plate or film. The shutter is the device which
controls the exposure, the opening and closing of l. T the blades being effected b_v the use of the bulb or
lever. The spring back is that portion of the
camera at the rear which recedes, allowing the
plate holder to be inserted. The back of the camera
is also reversible, that is, it may be reversed for

I either horizontal or vertical picture3 without dis-
turbing the camera after it has once been placed in
focus. The focusing scale is the graduated scale on
the bed, by the use of which correct focus may be
obtained
The rack and pmion is a device on the bed for
extending the bellows. It has a miiled..head which
may be easily manipulated by pulling out and turn-
ing forward The plate holder is a light tight device
for holding the sensitized plate in the camera
Each plate holder carries one dry plate. The
adapter is a device resembling the plate holder in
appearance and which holds the Premo filrn pack.
It opens like a book to accommodate the Pack.
It may be inserted in the camera just as a plate
holder is inserted.

LOADING THE STAR PREMO \TITH FILM.
'fake the film pack adapter and press outward
the two metal catches at the top, when the adapter
will open like a book. Place the film pack in the
adapter with the directions printed on the pack
turned toward you. Close the back of the adapter
ind return the catches to their first position.
Place the adapter in the camera as you would
a plate lrolder, inserting it in the siit back of the
ground glass and pressing into place. You are
then ready to make film exposures, following the
directions on the back of the film pack.View original page 6Page 7 · Read text
LOADING \T/ITH PLATES.
When giass plates are used, the plate holder i
I or plate holders must be loaded in a dark room.
That is a room from which all white light has been
excluded. Take into the dark room the camera, a Ii
dark room orange lamp, and the plates Light the I.{
lamp, Remove the slides from the'irlate holders l
by turning the catches at the top. Open the box d
of plates by cutting the paper around the edge of
the box. Remove the piates from the box one by
one and place them in the holders to be loaded.
with the dull side up. It is well to brush the face
of the plates with a camel's hair brush to remove
the dust. The slides are to be returned to the
holders with the colored side of the shoulder turned
out When plates are to be exposed in the Star
Premo, the plate holder is inserted and pressed
gently into position.
MAKING EXPOSURES.
Exposures may be divided into the foilowing
classes : Snapshots out of doors, time exposures ,f
out of doors, expcsures indoors, portrait work, and t-:
f lash-light work, There are certain rules and :t
cautions to be observed. which are common to all
exposures The subject of exposures is exten- T&
sively discussed in a larger booklet, entiJled the
AMATEUR PHOTOGRAPHER. which is a part
of this outfit. and may be studied with profit by the
operator. The general rules laid down for mak-

ing exposures apply alike to plates and films' In
order to make perfect pictures of any length of
exposure. it is necessary to have the proper stop in II
the'shutter set; to have the propei' speed on the I shutter; to have the indicator pointing at the I
proper distance on the focusing scale; to have theI slides withdrawn from the piate holder or from
the film adapter: to have the camera levell When these rules have been observed as carefully'
as possible, locate the object to be photographed in
the finder, and when in theproper position' squeeze
the bulb or press the lever with a firm, quick
motion. The picture has been made. These rules
should be studied in connection with the AMA-
TEUR PHOTOGRAPHER already mentioned'
HO\T ?O USE THE SHUTTER.
Careful study should be given to the manipula-
tion of the shutter. The instructions for operating
i.l the Auto shutter with which the Star Premo is
equipped are as follows :
I The plate at the bottom of the Auto shutter is?
the speed and diaphragm indicator. The upper line
t .of figures on the indicator represent the speed of
$r the exposure The pointer may be readily moved
T to any figure or letter upon the indicator and thus

second; B, bulb exposure; T, time exposure.
Thus, the pointer may be moved either to the right
or lefi and any desired length of exposure made.
The lever at the side of the shutter is the ex-
posure lever. Should an exposure of one-f ifth
second be desired, move the pointer to figure 5,
press the lever or bulb and the exposure is made.
Shouid bulb exposure be desired. move the pointer
to the letter B, when one pressure on the exposure
bulb or lever opens the shutter, which will remain
until the pressure is released when it will close
again. In making time exposures, move the
pointer to the letter T, when one pressure on the
lever or bulb opens the shutter, and after sufficient
time has been given a second pressure closes it.
The lower series of figures on the indicator rep-
resent the size of t6e diaphragm opening, No 256
being the smallest and No. B the largest. The
diaphraggr opening may be easily changed by
moving the pointer underneath to the figure repre-
senting the desiredaperture. The smaller openings
are preferable for time exposures, the larger for
instantaneous exposures
All lenses need wiping occasionally, They may
Be readily unscrewed from the shutter for this pur-
pose. Care should be exercised in cleaning them,
and the operator should be particular to replace
them in their proper position. E"tkt s. u g I
No oil should be used on the shutter.

MAKING INSTANTANEOUS EXPOSURES.
The Star Premo should be loaded with either
a film pack or loaded plate holder. In order to
take instantaneous pictures, the object to be photo-
graphed must be in the bright open sunlight, while
the camera should be shaded. Open the camera
by pressure on the concealed button 'dn top, and
the bed will failin position. Take out the bulb and
lay it across the bed. Gently press the two clamps
at the side of the front and drav, out the bellows on
the bed as far as possible. This distance will be
seen to correspond to the 1OO feet mark on the
focusing scaie. The camera js now at what is
called universal focus. That is, any object 1OO
feet or more away is in focus.
If it is desired to focus on an object nearer than
l0O feet, pull out the rack and pinion and turn for-
ward until the indicator on the front of tne carnera
is opposite the figure on the scale equal to the esti_
matedy'istance between the camera and the object
tobephotographed. Returnthepiniontoits original
position, and the camera is locked at its correct
focus. The camera may be also focused on the
slbject by the use of the ground glass. Open out the instrument to universal focus. Open the door I
in the back of the camera which reveals the ground
glass. Set the. shutter at time and open. The
camera rrfay now be focused on the subject by the
use of the pinion as before. Manipulate until the
lines are sharp and exact, and then push in thehView original page 10Page 11 · Read text

TIME EXPOSURES OUT OF DOORS.
All time exposures should be made with the
assistance of a tripod or support' The tripod is

PORTRAITURE \(/ORK INDOORS.
The subject should be placed from four to eight
feet from the'uvindow and about the same distance
from the camera. There should not be more than
one window in the room by which the light be
admitted and it should be so shaded as not to be
too strong. The camera should be placed on a
firm support at about the height of the ordinary
table. Compose the view with an appropriate
background that forms a contrast to the sitter.
Make the exposure as indicated in the table. In
making the picture, always use the largest stop
and give the longest permis_,sifls' gxposure. $v+EiJ' v't
PORTRAITURE \T/ORK OUT OF DOORS.
Excellent portraits may be made out of doors in
the shade of bushes or of trees and very short ex-
posure given. In time exposures made out of
doors, stop No. 64 should be used, the time of the
exposure changing from a twenty-fifth of a second
to three seconds, according to the light In this
kind of work, the smaller the stop, the sharper the
picture will be. The Star Premo is designed for
all kinds of photographic work, including flash-
light photography, etc., which is dwelt upon in the
Amateur Photographer, which is a part of this cut-
fit In the same book the subjects of developing
and printing are also thoroughly treateri.
