Learning Event 3:
DESCRIBE THE PURPOSE AND USE OF A CAMERA HEAD
1.
Along with your pedestals you have three different types of camera
mounting heads: Camera friction head, cradle head, and the camera cam head.
2.
The camera friction head counter balances the weight of the camera by
a strong spring. This spring can be adjusted to the specific weight of the
camera in use. This head was made for the old, lighter monochrome cameras,
but can now be used for the new lightweight color cameras.
3.
The camera cradle head assures excellent camera balance at all times
and thus prevents the camera from over balancing even at the most extreme
tilting angle. The cradle head can accommodate any camera without special
adjustments.
The cradle head is extensively used for the heavier color
cameras.
4.
The cam head uses two cams, one on each side of the head, to assure
balanced, smooth tilting and panning even with the heaviest camera. The cam
head is designed for the heavy color camera, but can also be used for the
new lighter color camera simply by changing the set of counter balancing
cams.
5.
All three types of mounting heads have horizontal and vertical locking
devices, and drag controls that can be adjusted to the desired drag
necessary for smooth, jerk-free camera operation.
6.
You should apply a light film of graphite oil on your wheels and cams
at least once per month.
