Speeding Blue Orb in Grand Central Station

Photo date: December 8, 2014.

In this photo we see a blue orb that appears to be moving very fast. Here is the larger photo:

Here is a closeup cropped from the above photo. Note the "triple displacement" effect, an effect which photographers call ghosting. It is caused when the speed of an object exceeds the shutter speed of a camera. Since the camera had a very fast effective shutter speed of about 1/1000 of a second, this orb was probably moving very fast, much faster than any insect would move.

Contrary to assertions of skeptics, this type of effect is not a very rare effect, but instead a very common effect when photographing orbs.
