Cool optical illusion!

[Joanne98]

A climber in Poland has taken an astonishing photograph of what appears to be a ghostly figure emerging from the morning mist on the side of a mountain.

The optical illusion, pictured at dawn in the Tatra mountains, is actually what is known as a 'Broken spectre', a phenomenon which occurs when there's a low sun shining behind someone looking downwards into fog from a ridge with their shadow projected forwards.

The illusion can appear on any misty mountainside or cloud bank, or even on some occasions, from an aeroplane.



The extraordinary sight involves the light behind a climber casting their shadow often in an odd triangular shape.

The shadow can also fall on water droplets of varying differences from the observer's eye causing confused depth perception.

Amazingly, the ghostly figure can sometimes appear to move rapidly when the cloud layer moves or there are variations in its density.
