The Tilt Head — General
Operating
Even if the Steadicam is slightly out of
perfect dynamic balance, it’s a whole lot
easier to hold the post vertical than at
any other angle, especially when panning
and accelerating - which we tend to do
a lot when operating a Steadicam. The
tilt head keeps the post vertical in many
situations, making it easier to operate and
keep things level.
Another benefit of the tilt head: a whole
new class of whip pans is now possible.
All whip pans are done in dynamic
balance with the post vertical. Previously
this meant that the lens was always
horizontal. With the tilt head, the lens can
be angled up or down as much as fifteen
degrees and the operator can still make
extremely precise fast pans. Using the
tilt head will increase the precision of any
pan with a lens angled up or down – fast
or slow.
Setting the tilt
The operator sets the tilt by releasing the two clamps and manually repositioning the
camera to the proper angle.
The post remains vertical and the rig stays in (or close to) dynamic balance. Only
minor static rebalancing is normally required, but exactly how much depends on the
camera, accessories, sled length, monitor position, etc. In all cases, bringing the sled
back into static balance by moving the camera will return the sled to dynamic balance
as well (see page 28).
Long mode pans with the lens looking
down - say at a crowd - used to be
exceedingly difficult or impossible, due
to the large spatial translations of the
battery, monitor, and camera. But the tilt
head leaves the post vertical and therefore
eliminates this spatial translation, and
makes these pans routine.
Low mode and very low mode pans are
also much easier and more precise.
