Panorama of the Duomo and square in Firenze, Italy.
Before you slag the distorting verticals and get all funky on me, some explanation regarding the image:
34 images, 10MP, 360 degrees, with a sigma 10-20 lens @ 10 mm.
The building on the right is about 8m away from me, and about 25m high (notice it's all in the image ?), the building on the left is about 16m away from me, and probably 35m high, with the tower next to it even higher, all in the image.
This was my whole idea, to at least have it in, even though it was always going to be contorted !
Took autopano the better part of a day to think about this one, and then I still had to add several 100 control point to make the tower and parts of the basilica fit together.
