Pegasusinc, do you rely completely on Photosynth to automatically capture new photos, or do you manually tap the screen to snap photos when the automatic snapping isn't taking place?
One critical idea for successfully shooting a panorama for any panorama stitching software is to keep your camera's lens as close to one spot in the air as possible. What I mean is that you should rotate the camera around the lens as you look in different directions, instead of moving the lens around the camera or the camera around your body at arm's length. Since the Photosynth mobile panorama app only creates and views panoramas, this will apply here as well.
When you are using the Photosynth app for Windows to create photosynths (instead of panoramas) a critical concept for capturing a 3D reconstruction of an object or scene is to view it from many different angles walking all around it, but for panoramas made with ICE, Photoshop, + the mobile app, keep the camera in one place.
