WINDING AND UNLOADING
THE
FILM (Fig.

III
S is a motor-driven camera, the film will
automatically
advance

shows
the
"E"
sign, open
the Camera
Back,
take out
the
Film
Holder's inner
frame
,
and
unload
the film.
Next,
to prevent
the
film
from loosening
,
seal
it tightly
with the End Seal.
V.
CAMERA
MOVEMENTS
:(.
GX680
III
S has no camera movement functions.
In normal
photography,
the lens
optical axis
passes
through
the
center
of
the
film at
right angles. Camera movements are used to take
the
optical
axis away from film
center,
to cross the lens optical axis and film
surface
diagonally,
etc.
to control image perspective
and
sharpness.
They
let
you change
the
shape
of objects in your picture,
shoot subject
that
have
depth
to them but
which are sharply
focused from
one end
to
the
other,
as well as control
the position
of objects in
your
picture without
changing camera
position or
angle.
The
main camera movements are
the
tilt and swing which involve an
optical twist and turn, and the
rise
,
fall
,
and shift which involve a parallel
movement of lens and film, and the generic term that
encompasses all
these
deviations from normal is
"camera
movement"
.
1.
RISE AND
FALL (Fig. 53)
These movements are made by loosening the Rise/Fall Knobs located
on
both
sides
of the lens mounting and raising or lowering the lens
face
parallel with the line of the film
plane.
The rise is
an
upward
,
and
the
fall
a
downward movement. They
are generally
used to make
tall buildings
appear vertical
in your picture
and
to improve the figure
of portrait
sub-
jects
.
