I continue to be impressed by the Google iPhone photosphere application. Shooting a photosphere is time consuming. You have to stand in one spot and turn around making three passes. I sometimes get dizzy with all the turning. A single photosphere takes about twenty frames. The panorama software then glues it all together and does a pretty decent job considering the vast contrast range. The application always seems to find the correct horizon. There are stitching errors but then it’s always difficult to eliminate such errors when gluing frames taken with one lens at different times. Getting good photospheres takes practice just like every other type of photography. This is my favorite so far. You can view this image in a 3D viewer by clicking on this sentence.
