Hundreds of models wearing only white body paint walked across a stark desert expanse in southern Israel near the Dead Sea on Sunday, as part of the latest photography project from American artist Spencer Tunick. Tunick, dressed in black, stood on the roof of a recreational vehicle and issued commands on a megaphone. The year-old photographer visited Israel as a guest of the tourism ministry to portray for the third time the shrinking Dead Sea via nude subjects. Tunick depicted more than nude models a decade ago on the shores of the salty Dead Sea, which is receding at about a metre a year.
