Faster Than a Dashing Commuter

Photo date: March 11, 2015. Photographer: Mark Mahin

In this photo taken in Grand Central Station in New York, we see yet another example of a fast-moving orb.

The photo shows what photographers call ghosting, produced when an object moves much faster than a camera's shutter speed. Since the effective shutter speed of the camera was about 1/1000 of a second, the white orb shown here must have been moving very fast. See the posts on this site labeled "speeding air orb" for many similar examples.
