After days trying... I have made a spherical panorma.
I am using the following :
nikon d200 with tokina 12-24
nn3 + rd8 rotator
And this software :
But its not perfect.. I am having troubles stitching the panorama, mostly PTGui can stich almost all the images, except for the nadir and zenith photo. I give the control points in by myself in that way. (why ptgui doesn't see the control points of the nadir and zenith?)
After doing that, ptgui makes the panorama, and I make a 360 movie of it with pano2vr.
