I have been struggling to stitch a few pole pans I took that suffer from
parallax error. They would probably benefit from this method. The
struggling got me thinking. This would not be unnecessary if there were
two horizontal and vertical shifts that PT could use. One before
correcting radial distortion like we have and one after transforming to
It is currently difficult to use d & e parameters to shift an image to
fix parallax error because it plays havoc on the a, b, & c parameters.
It is necessary to correct is two stages. If there were two set of
shift parameters then it could be done in one stage.
