'Phantom' by Peter Lik sold for $6.5 million to a private collector.

The world's most expensive photograph has sold for $6.5 million to a private collector. The photograph 'Phantom' was taken by fine art photographer Peter Lik, and was joined by sales of his "Eternal Moods" for $1.1 million and "Illusion" for $2.4 million for a total of $10 million.

According to Lik's representatives, these three sales in addition to the previous sale of his "One" for $1 million in 2012 means Lik now lays claim to four of the 20 most expensive photographs sold in history. "Phantom" is a black and white rendition of his "Ghost" photograph, and though Lik doesn't often produce black and white imagery, he found it compelling in this case, saying:

"Certain textures and contours found in nature lend themselves beautifully to black and white photography. The intensity of contrasting light and dark spaces was surprising, but made for some of the most powerful images I've ever created."

The buyer has requested anonymity, but is a 'long-time collector of Lik's works', according to his or her representative Joshua Roth. Skeptics have speculated that the sale is nothing more than a marketing tactic, and the photo has drawn some less than charitable commentary. What do you think? Tell us in the comments.
