A bodypainter uses UV paint to create electrifying masterpieces of stunning landscapes on models. John Poppletons vibrant Bodyscapes feature bright savannahs, lightning storms and vivid galaxies leaping from the bodies of his subjects. The artist, who lives in Wellsville in Utah, USA, uses a black light on his paintings to make them look as close to real life as possible. He predominantly uses female models and often paints across their backs to give him the largest surface area to work with. Here: “Bamboo Mist”. (Photo by John Poppleton/Caters News)
