Modifier
The Camera Correction modifier applies
two-point perspective to a camera view. By
default, camera views use three-point perspective,
in w hich vertical lines appear to converge with
height. In two-point perspective, vertical lines
remain vertical.
The amount of correction you need to use depends
on how steeply the camera tilts. For example, a
camera that lo oks up f rom g round level to the top
of a high building will need more correction than
a camera that looks toward the horizon.
Note: This modifier do esn’t appear on the Modify
panel’s Modifier List.
