During the rainy season, the flats are submerged in 6 to 20 inches of perfectly still water, turning the shallow lake into the world’s largest mirror. In the dry season, when Wu visited, the salt crystals dry into an intricate latticework of tile-like polygons stretching away to the horizon in every direction. “I was really taken by this composition of pure horizon,” Wu says. “It’s just the sky and the landscape.”Shooting the salt flats was the culmination of a week-long Bolivian road trip Wu and two companions took last July. Between the freezing nighttime temperatures, high altitudes (the Altiplano averages 12,000 feet above sea level), and long drives, the team got little sleep. “We were cold, we were light-headed, and doing anything physical was very hard,” Wu recalls. “There were times when I really struggled.”
But the hardships paid off when the crew finally reached the salt flats. Because it was the dry season, most of the Salar de Uyuni looked like a geometrically patterned moonscape. Still, Wu was lucky enough to find a standing puddle large enough to capture the rainy-season mirror effect, too. In addition to more traditional landscape photography, Wu created several of his signature aeroglyphs—glowing geometric shapes that float mysteriously in the sky. Wu draws the aeroglyphs by piloting LED-equipped drones in precise patterns while keeping his shutter open to create a long exposure.Over the course of the road trip Wu documented a variety of Bolivian landscapes ranging from sandy deserts to rocky palisades, but the Salar de Uyuni emerged as the highlight. “If it were in the US, it would be swarming with tourists,” he says. “Instead, we had the whole thing to ourselves except for the occasional farmer and a cow.” The salt flats are rich in deposits of lithium, a key element in smartphone and electric car batteries, but lithium mining operations are still in their infancy thanks to the region’s inaccessibility and the reluctance of recently ousted president Evo Morales to greenlight foreign investment.
Throughout the trip, Wu used a Phase One XT, a compact medium-format digital camera that allowed him to take ultrahigh-resolution images on the go. Back in his studio, he used software to tinker with the images until arriving at the final product. Wu thinks of photography as “painting with light” and doesn’t fetishize authenticity. “For me, everything’s a tool,” he says. “The camera’s a tool, the computer’s a tool. Just so long as the technology and the tools don’t overwhelm the vision.”
