minute,
the complete action taking place
during
one hour will be
shown
on the
screen
in
3.3
seconds
if the projector is
running
at
18
frames
per
second
(speeded
up
1080
times).
If you use
a
filming
speed between 6 and
approximately 2
frames per
second,
it is
.
not
absolutely
necessary for the camera to
be
attached to the
tripod
.
However, you
must hold the
camera
very steady,
avoid
panning or tracking with the
zoom
lens
and
remember
that in order to
obtain
1
second
of
viewing time
on
the
screen
you must
shoot
for
3-9
seconds.
Genuine
time lapse
cine
photography, on
the
other
hand,
calls
for the
camera
to be
mounted
absolutely rigidly on a
tripod. As
a
temporary measure, the Nizo
can
be
rested on
its
handgrip,
but
remember
that
this will
limit
you
to the field of view
ob-
tained
where
the
camera
happens to be
resting
.
Animation
If
Single
frames
are exposed at prolonged
intervals, you
will have time to rearrange
th
e
position of
inanimate
objects between
each
exposure. For
instance,
you could
raise or
lower
the arm of doll by a small
amou
nt
each time or push a matchbox a
small distance
furth
er
across a
table
-
these are
just
two simple examples.
When
th
ese
single exposures are projected at
the
normal continuous
speed
of
18
frames per
second,
the inanimate objects come to life
on
the screen. The doll waves her
arm and
the match box travels to
and
fro
across
the
table.
For
all shots of this type, the camera must
be mounted
absolutely
rigidly. It is best for
it to be
attached
to
a
substantial tripod
.
If
the
camera
position is moved
accidentally
halfway through
a shot,
it is best to change
to
a shot
taken from
another
viewpoint or
at
another focal length in order to disguise
the
jump in the
action. The
camera
shutter
can
be operated manually with a
cable'
release or by means
of
the
electric
remote
release. However, you
can also set
the
automatic single
frame device to make
ex-
posures at suitable
intervals, so that you
need not move backwards
and
forwards
constantly between
the
camera
(to
expose
each single
frame)
and
the object you
are
filming
(to
alter
its position
slightly).
All you
need to
do
is to
select a
filming interval
at
filming
speed switch 2
which
gives
you
sufficient
time to rearrange
or
move the
object you are filming.
Flash
illumination for time lapse filming
Since
the interval between
exposures in
this type
of single
frame filming
is quite
long,
each separate exposure can
quite
eas
ily
be
illuminated
by
means
of an elec-
tronic flash
gun of adequate
power,
which
at the same time supplies a
natural light
at
a color temperature similar
to that of
day-
light.
A
further
advantage is that objects
sensitive
to heat (plants, thin
gels
for
ani-
mated films,
etc.)
are not
continually
ex-
posed to the heat
of
spotlights or
photo-
floods. Your Nizo
camera
is therefore pro-
vided with
a connection
for the flash gun
synchronizing
cable (at far left of camera
base).
Connection for electronic flash
The
electronic flash
unit must
be
of
ample
capacity since
18 flashes
are
required to
illuminate one
second's
filming
and
should
also
be
capable of repeating
its flashes
frequently
enough
for lengthly
series of
single shots to be
filmed. The flash
gun
must have
recycled,
ready for the next
shot,
before the
camera
timer has
advan.ced
the
film.
Braun
offers three electronic flash guns
(all
equipped with a swivel
reflector) which
meet the
requirements.
The
Braun F 800
is
a
large,
two-section
professional unit which
can supply
up to
400
flashes
(depending on
th
e
storage
battery used)
at minimum
