Follow the steps below, and you are able to create your own panorama with Panoweaver easily and fast. In order to stitch panorama with Panoweaver, you need digital camera, fisheye lens, pano head and tripod. Refer to Panoweaver compatible equipment.

Pano Head:
Pano Head is also called tripod panoramic head, or rotator. To understand the function of pano head, "nodal point" should be explained first. The nodal point is a special point in space, where light entering the lens converges into a point and then diverges to impact on the recording medium. As one rotates a camera and shoots a sequence of photos to later be stitched together, all of the photos must be shot with the camera rotating about its nodal point! The pano head is just used for this purpose.
