I used this technique a few years ago to make an interesting photo. I was at the IVRPA (International VR Photography Association) meeting in San Francisco and we did a photoshoot walk across the Golden Gate bridge. In keeping with the group's interest in panoramic photography, I was making a spherical panorama on the bridge. Of course, there are tons of people and cars on the bridge, but I wanted it to appear empty, so I took a bunch of images at each angle where it was needed. It worked pretty well and stitched together just fine. I call it Golden Gate Ghost. I am attaching it below, both the original stitch and after making it more ghostly looking.
