PanoTools NG: Re: Can I fix line errors in PTGui? j.houghton@... 2014-Nov-06 09:20:38
Having now checked the images, there is a small amount of both horizontal and vertical parallax visible, This needs to be checked with something really close to the camera set against a background really far away.  Using two objects indoors doesn't work as well since both objects are then relatively near to the camera and both are affected by parallax. My tutorial that Willy referred you to suggests a strip of sticky tape on a window looking out onto a distant view, but don't focus on the near object - use a small aperture.   

 Your nadir shot is largely redundant as it offers very little extra useful coverage.  Nevertheless, for test purposes it is helpful to take two nadir shots, rotating the head 180 degrees in between. Stitch them to PSD layers and check for parallax like this: http://ge.tt/6nqUsi32/v/0?c http://ge.tt/6nqUsi32/v/0?c .  This is better than simply centering the centre screw in the camera's viewfinder.
