Ever
see
slow
motion
footage
of
a
bullet
ripping
through
an
egg?
Those
shots
were
obtained
with
a
high
speed
camera.
Used
primarily
for
special
effect
shots,
these
expensive
cameras
are
rentable.
The
internal
movement
is
radically
different
from
a
typical
claw
movement
camera.
They
work
like
this,
film
is
fast-forwarded
through
the
film
gate
at
an
incredible
speed
while
a
very
fast,
rotating
prism
performs
the
function
of
a
shutter
without
ever
touching
the
film.
Contact
between
the
film
and
the
camera
is
limited
to
the
high-speed
transport
rollers
that
can
move
1000
feet
of
film
past
the
gate
in
a
heartbeat.
It
takes
time
for
the
debris
of
a
real
explosion
to
hit
the
ground.
Miniature
explosions
have
to
be
slowed
down
to
give
the
explosion
"scale"
to
maintain
the
illusion
of
size.
These
kind
of
slow
motion
effects
are
the
primary
applications
for
high
speed
cameras.
