To achieve 100% synthy taking over 300 photos of this cathedral is incredible! The point cloud also turned out really interesting considering that no overview shot could be taken from a high point nearby.
Particularly pleasing was the way Photosynth constructed the rounded end of the cathedral viewed from the Philharmonic end.

sadly although the synth is 100% the point cloud is nothing like the cathedral really is...a mystery is the only way to describe it...anyway...
