This is a
stereoscopic view. To view the images in
3-D, slightly cross your eyes until a composite image forms in the
middle. When this happens, attempt to position the composite photo
over one of the two original lamp photos. When you've achieved the
overlap the images combined should form a 3-D photo. For a small
percentage of people (5 -10%) this affect won't work. It may take a
little persistence for others.
