Remarkably a photograph by Australian/US photographer Peter Lik, a wonderful trick of light taken in Arizona’s Antelope Canyon recently sold at auction for a remarkable and record breaking $6.5 MI.  It is now the most expensive photograph ever sold. And it reveals a spectre that would have made Conan Doyle blink with credulity. To the extent that the art market sets the standards, this moves photograph to a new echelon in the artistic hierarchy.
