Two-tone Speeder Orb

Photo date: December 22, 2014.  Photographer: Mark Mahin.

In this photo taken at Grand Central Station in New York, we see an orb that displays what photographers call a ghosting effect, caused when an object moves faster than the shutter speed. Since the effective shutter speed of the camera was about 1/1000 of a second, an effect like this indicates an orb that is moving very fast.
