This photograph was taken by Panayiotis Lamprou and is entitled Portrait of my British wife from the series Human Presence.

The woman in question is Mr. Lamprou's wife, photographed on the island of Schinousa at their summerhouse. The photograph was never meant to be on public display, however, it won second place at the Taylor Wessing Photographic Portrait Prize in 2010 at the National Portrait Gallery in London, UK.
