Info

The rule number one when filming somebody talking "a talking head", typically as seen on TV news, interviews, diskussions etc, is that center of lens should be at eyeheight.

This gives us a "neutral expression". Going higher or lower can be done for effects, but if the message of the talking person is the main subject, then neutral expression is desirable.

In a typical studio etc situation one could expect to sometimes, now or in the future, have short persons sitting down, or at other times tall persons standing.

In practice this means that needed vertical range of "Center Of Lens Above Ground" (COLAG) should be from about 1 meter up to about 2 meters.

This means that a robotic system should be able to cover this vertical range directly, without a rebuild, in order to have an efficent and adaptable worksituation.

Please note that PTZROBOT Pro and Studio Line systems all have 100 cm stroke, and the ability to also go low.
