44
the moving main subject
in
the viewfinder.
You then release the
shutter
while still twist-
ing. When
you
use this technique,
the
main
subject
should be sharp even
at
slow
shutter
speeds and
the
image
of
the background
is
blurred according
to
the speed
of
the
panning
movement. This hightens the feeling
of
motion
in
the picture.
Effects
of
Changing the Aperture
The
lens
aperture
does
not
only control
exposure
but
it also has an
effect
on
the
photograph
as follows:
In
example C,
the
aperture was set
at
f/5
.6 with
the
shutter
speed dial adjusted
before
shooting
.
In
example
0,
a
f/16
setting
was used
to
clearly
demonstrate
the
diffe-
rence.
In
C,
the
miniature cars
in
the
back and
front
are blurred and only
the
miniature cars
in
the
central area are
in
focus.
In
0,
most
of
the
miniature cars are sharp and clear. Thus,
the
lens
aperture
has a marked
effect
on how
much
of
the
picture
is
reproduced sharply.
