Balancing the head

10 Balancing the Vision 6 head achieves two objectives. Firstly, when a head is correctly balanced the
operator will need a minimum amount of even effort to move the head. Secondly, once balanced, the head and
its payload can be set to any tilt position and the head will maintain this position with "hands off".
11 The graph (Fig 2.3)
may be used to ascertain the suitability of the head for any given combination of camera, lens and
accessories. The shaded area of the graph corresponds to those loads/C of G heights that can be balanced
over the full tilt range. The areas to the right indicate the progressively reducing tilt range over which the head
can balance higher loads.
