Create 360-degree panoramas (Photoshop Extended)
Combine Photomerge with 3D features to create a 360-degree panorama. First, you stitch together the images to create a panorama; then you use the Spherical Panorama command to wrap the panorama so it's continuous.
Be sure to photograph a full circle of images with sufficient overlap. Photographing with a pano head on a tripod helps produce better results.
