PART II.
SECTION TWO
The Shutter
The shutter controls the rapidity with which
the picture is taken, and the r-apidity must vary
according to the strength of the fiaht and th'e
size of the opening.
Bubbles in Lenses
It is practically impossible to eliminate small
air bells or tubtles in the manufacture of
optical glass' for anastigmat lenses, because of
the faci that in the process of manufacture
various chemicals must be fused together a
given length of time at a certain d9gree. At
[n" critica]l moment the process must be stopped
whether all the air has been driven out or not.
This is necessary if the optical qualitieis of the
glass are to be retained.
The small bubbles are caused by the air left
in the glass, and should be taken as a gaafantee
of quafity rather than a detriment to a lens, fo1
the^ actu-al loss of light is inappreciable, . and
the bubbles,'effecteven when near the surface, have
little or no on the optical quality of the Acme Speedex Shutter
image or the speed of the lens. On the small circular disk at the top of the
shutter are indicated the various exposures of
which the shutter is capable, expressea in frac-
tions of seconds. Ths speed is regulated by
revolving the disk so that the pointer indicates
the desired exposure. The letters B and T,
standing respectively for bulb and time, also
appear upon this diak, and are explained under
the proper headings for bulb and time exposures.

Opening the Front
To take instantaneous pictures the object
should be in bright sunlight, but the camera
should not. The sun should be behind the
back or over the shoulder of the operator.
