better by including the shifted nadir in the optimization!
Probably this problem was caused by my technique. I have a tripod with
an invertible head, so I took the nadir by inverting the head. The
viewpoint displacement was therefore about six inches vertically instead
of to one side. I don't know if this is allowed by PTGui even when I
untick the "optimize using" box and tick the "viewpoint" box for that image?
Currently I am using Pano2VR to create cube face JPGs, cloning out the
tripod in the nadir face, then creating a SWF file from these cube
faces. This also solves the problem of making the same patches in three
bracketed HDR exposures.
