Seb,

I'm using autopano-sift-c.  Assuming that the display is only cosmetic, why is 
the right side of the pano flipped upside down and the left side the correct 
orientation?  I assume it's because of the one image.  The problem is, while 
this pano is a fairly simple error problem, other panos will get images flipped 
every which direction.  Is the automatic point control really this bad (ie, 
autopano-sift-c)?
