"That's why I've decided to do the work on Saturday (the Jewish Sabbath), so no one would be walking by and see a naked person half a mile away and be offended," he said.
The Dead Sea's surface level is plunging by about 39 inches (a meter) each year, and the shoreline has receded by more than 0.6 miles (1 kilometer) in places, according to some estimates.
For Ari Frucht, who initiated the project and has toiled over its preparations for the past four years, a work by Spencer Tunick could help raise awareness of the sea's condition and galvanize Israel's government into action.
He believes there is another aspect, too, to the Jewish state hosting such a shoot.
"The world needs to know that Israelis are not religious extremists," he said ahead of the event.
Besides involvement in public disrobing, the installation provided Chai Amir, a 35-year-old resident of central city Bnei Brack, an opportunity to do something for a cause he believed in.
"I'm glad I was able to take part in an event aimed at saving the Dead Sea," he said as the shoot wrapped. "You can really see how the waterline recedes every year."
