Pivot point
The Pivot Point is the point at which the rotations begin. In the default configuration, the Pivot Point is
located at the geometric center of the image or nodal point of the camera (see below). In other words, the
rotational axes intersect at this point.
Yo u c a n m o v e t hi s Pivot Point along the individual axes and thus move the center of rotation, as illus-
trated by the following example:
Move x pivot point to the left
If you wish to rotate the image around the left-hand vertical edge, set the x Pivot point to -50 percent
(half the image width). The Pivot Point moves from the center to the left-hand edge. Now set the y Spin
control: The image opens up like a window shutter.
Now shift the y Pivot point to +50 percent: the point is shifted upward by half the image height to the
upper left-hand corner of the image.
