[Leica] Two Panos of the Staircase of Elizabeth Bay House - lens distortion

[cummer at netvigator.com (H&ECummer)]

Hi Richard,
Very good point about the type of mapping used. Cylindrical didn't  
work - it's what I prefer - so I used automatic and that produced a  
dumbbell shape - top and bottom - which may be contributing to the  
distortion that Nathan sees. But, as mentioned previously, the shape  
of the skylight is originally elliptical already.
Cheers
Howard
