This spooky image shot in an underground cavern in Arizona's Antelope Canyon by Australian, Peter Lik, was sold by the photographer for $6.5 million in December 2014 making it the most expensive photograph ever sold.
Of "Phantom", Lik said: "The purpose of all my photos is to capture the power of nature and convey it in a way that inspires someone to feel passionate and connected to the image".
The anonymous investor is a long-term fan of Peter's and also added his "Illusion" ($2.4 million) and "Eternal Moods" ($1.1 million) to his Collection.
Prior to that, the 'title' of most expensive photograph ever sold was 'Rhein II' by German photographer, Andreas Gursky taken in 1999 and sold in 2011 for $4.3 million to an anonymous collector.
'Rhein II' was the largest of of six photos of the River Rhein and Gursky controversially digitally edited the image to remove details including a factory building & dog-walkers.
Gursky defended his editing, saying, "Paradoxically, this view of the Rhine cannot be obtained in situ, a fictitious construction was required to provide an accurate image of a modern river."
