Hi folks...i am using for a year NN3 with my Nikon D300 and Tokina 12-24 for shooting panoramas mostly in 360 degree..

Now I have 10.5mm fish eye and I am trying to shoot 360 x 180 degree panorama but there is a huge problem.

I do 6 shoots in horizontal, then I tilt the lens up for zenit but for nadir, I remove the Nikon from NN3 and shoot straight down for Nadir...and that is a problem.

I see my legs...and I can not stiitch panorama? It is Ok if I am on the grass or something like that - I do cloning in photoshop and that is perfectly stitched using the Autopano Giga....but it is mission imposible if I am in a church or anywhere where there are a tiles with texture on the floor...and ad to the problem my legs, besides tiles..and I can not clone that picture for nadir....and I can not stitch

What to do..how to shoot nadir in flor covered with tiles or textures and to avoid my legs?

Thanks a lot for help
