Variable shutter control lever
The
variable
shutter
is a mechanical
device
which
independently
from
the diaphragm,
modifies
the film

time
as
desired.
It
is thus possible to go from maximum
aperture
to complete
black-
out,
permitting
fade-ins
and fade-outs,
superimpositions
and
lap-
dissolves.
Shutter
aperture variations
are controlled
by means of a
lever
(20)
whose use is depicted
on
page
