Date of sighting: May 25, 2013
Location of sighting: Muiderslot Castle, Netherlands
Literally faster than the eye could follow, an unusual object was accidentally photographed above the landmark Muiderslot Castle in the Netherlands.
On May 25, Corinne Federer and her mother visited the medieval castle, built in 1285 near Amsterdam. Federer, a supply chain manager for adidas in Amsterdam, and an avid photographer, was shooting High Dynamic Range, or HDR, photos of the castle.
"In order to create HDR images, you take three or more exposures -- this one happened to be five -- and you shoot them all at the same time, because you then overlap the images and it gives you the full spectrum of light, which your camera can't capture but your eyes can," Federer, 43, told The Huffington Post in an exclusive interview.
