I use NN3 + RD8 with Canon 40D and Peleng 8 mm fisheye lens. I make 360 panoramas with 6 shots - 4 sides, top and bottom and merge them with Easypano Panoweaver. When I do the bottom shot, the "hand", holding the camera, is clearly visible (http://www.mikasbinkis.lt/pano_bottom.jpg), as it is visible in the stiched image. Could you spare any tips that would help me to hide the "hand" ?
