another image is loaded. Not perfectly registered and with different
contrast. This image doesn't add more details. It only increases the image.
That's no surprise, since most likely this wasn't shot at f/4 which
would be needed to produce an effective resolution of 320 GP for a
spherical panorama. Higher aperture values cause more blurring due to
diffraction. See http://wiki.panotools.org/Diffraction#Resolution for
details. The extender doesn't increase the resolution since the
effective aperture is changed as well: The table shows the same values
for 800mm f/8 and 400mm f/4.
This is the end of the gigapixel race.

effective f/5.6 at 800mm. The diffraction limit for a spherical panorama
shot with that parameters is almost 900 gigapixel. Hence the resolution
of the panorama is well within the physical limits. Sorry for false
