The Compound Head
This head solves some problems involving long lens work. It makes small accurate
moves possible and provides better support for heavy lens/camera combinations.
It also allows you to use a fluid head that you already have the "feel" of.
If you are shooting with an 800-mm lens a smooth slow pan is difficult. With
this head you can make a one-degree camera move with a 3 to 6 degree move of
the panhandle. This ratio is adjustable. The higher the ratio, the less total
move is possible. If you are making large, faster moves you don't have the need
for fine adjustments and you can use your regular tripod head.
It is important to orient this head so that the pan and tilt ability includes
the whole possible field of action. Remember, the higher the ratio the less
the range of possible view.
This head also provides two points of suspension and helps reduce disturbances
from wind, camera motor vibration, and movement from the operator's body.
With this head I suggest using only heavy weight legs. The braced aluminum center
post TV style are excellent. The additional size and weight of this head make
it more top heavy on standard Mitchell legs. As with other heavy camera I would
recommend not moving it as a whole unit. Remove the camera.
As with any new piece of equipment, I suggest that you practice setting up and
using the head before you are on a job under the pressure to make a shot.
I've used the prototype to this for about 10 years. It takes a little longer
to set up, but it is really worth the time for the really long lenses.
The front head that the camera is supported on can be an old friction head or
even home made as long as it is strong enough and has no play. The panhandle,
dove tail or extension from the front head is moved by a second fluid head that
the operator has the feel of. The linkage between the two is shown. Please send
in your solutions so we can share them with others.
The linkage shown can be replaces with a hinge to the top plate in line with
the two heads to replace the two upper Heim joints. Small heads can be coupled
with a rubber connector such as a rubber ski pole basket.
I put this head together out of parts I still have. Think carefully about what
you have available and design a "PROFESSIONAL" looking one for your self.
