1. Freezing Motion
Usually a certain shutter speed
is
chosen
to
freeze the motion
of
a subject. The faster the
subject
is
moving, the higher the shutter speed
required
to
stop the action. While
it
is
possible
to
freeze the motion
of
a pedestrian at 1/
60
second, you need 1/
1000
second
for
a moving
train. The motion
of
the bird
in
this photo was
frozen at
1/
1000
second.

2. Blurring the Subject's Motion
Blurring part
of
the picture intentionally can give
a convincing sense
of
action. To blur the sub-
ject.
simply set a shutter speed which
is
too
slow
to
freeze its action.
In
this photo
it
was
blurred at 1/
125
second.
You can also blur the background by
"panning."
Choose a
shutter
speed suitable
for
the subject's
motion
and release the
shutter
as
you
follow
the
movement, turning
the
upper part
of
your
body
. See
p.
87
for
a colorful example.
