Dancer Photosynth

Tried another photosynth with the same location, light conditions and number of images as the owl photosynth. Only 44% synthy - photosynth won't move around the back of the object. Maybe because the feature points at the back are quite different from those at the front? Maybe more images in the transition zone will help...
