Sigmund,

The camera separation depends on the focal length of the lens. The default
for POV is the equivalent of a 50mm lens, I think. With a "normal" lens of
35mm to 50mm the camera separation should be about 1 unit for every 30 units
between the camera and the closest object. In this case it would be the
edge of the target. Since the target is at an angle to the camera it is not
so simple, but you can approximate without doing the math. Where is the
target
located relative to the camera? If the target is at 0,0,0 and the camera is
at x*-50 then the rule of thumb would give a camera separation of 1.6667
units (cm).
Since the target is angled toward the camera, a separation of 1 should do
fine.

ps. Is the target person anyone we know?
