Robert Hurst tells The Picayune Item newspaper that he shed his clothes because he believes skin is the best canvas to show spirits' orbs of energy.
The 47-year-old says he only intended to remove his shirt, but he took off all his clothes - a move he now calls "stupid."
Authorities had set up a motion-activated camera to try to catch vandals. Shane Tucker, the chief deputy in Pearl River County, says Hurst is not accused of vandalism, but the camera caught an unexpected image of Hurst naked.
Hurst faces a misdemeanor charge of indecent exposure. He posted $500 bond after turning himself in Friday.
