Night photography: Half of a school bus (ribs)

Half of a school bus (ribs) -- by Joe Reifer

Five images at 2 minutes f/8 ISO 400 were combined for this cumulative 10 minute exposure. The exposures were short because I was trying to capture lightning strikes above the ribbed metal debris piled in this half of a school bus. Unfortunately the lightning was too low to the horizon to appear in the shot.

Can you identify what is different about the camera position on this shot than the typical junkyard photo? There were no tricks in post-processing -- it's something physical about the actual camera placement.
