Instructions for the Operation
of the Kodascope
O successfully operate the Kodascope, the instructions in
T this manual should be carefully read and followed. The
Kodascope is accurately adjusted and is very simple to 'bperate,
but unless the few things which have to be done by the operator
are done correctly, there will be danger of injuring the film.
Before threading the film, it is best to familiarize yourself with
all the operations mentioned in this booklet. Then thread the
ample film, which you will find on the extra reel, and practice
projecting and rewinding the film.
In the Kodascope, the sprocket draws the film from the supply
r el and feeds it to the pull-down. The pull-down draws the film
intermittently past the aperture in the gate and the same sprocket
takes the film from the pull-down and feeds it to the take-up reel.
Illumination of the Room
Before using the Kodascope the room in which the pictures are
t be shown should be darkened sufficiently to allow the Koda-
cope to project a brilliant image on the screen. This does not
mean that the room should be totally dark. If 't he lights are
properly placed, the room may be sufficiently light to read in,
after the eyes of the occupants have adjusted themselves to the
subdued lighting.
A floor or table lamp with a clark colored shade may be left
lighted while the Koclascope .i. in use if the lamp is placed back
and to one side of the audienc . Entirely satisfactory projection
will be obtained if the light does not shine directly in the eyes of
Ll. e audience and does not perceptibly reduce the brilliancy of
Lh image on the screen. If the lamp throws too much light at the
t p, a piece of brown paper cut to size can be inserted in the top
of the lamp shade. Very often the lights in rooms adjoining that
in which the Kodascope i. used do not impair the brilliancy of
the projected pictures.
Kodascope Screens
For the best results one of the Kodascope Screens should be used.
They are made especially for projection with the Kodascope.
The reflecting surface of these screens is silvered, giving the pic-
ture much life and brilliancy. It is not fair to your Kodascope or
to your eyes to try to use a sheet or a blank wall for a screen;
they cannot give good results. See descriptions on pages 46 and 47.
