When he's not taking shots of mountain bikers in the summer, you'll probably find photographer Fabrice Wittner near a slackline. He says that the sport rules his summers, not just as a subject for photography, but because it is one of his many passions. As you can see from his shots, slacklining requires an immense amount of balance and strength, as well as incredibly steady nerves.
“The reach of balance is a constant fight that we bring to a next level with highlining,” says Wittner. “Then the line is rigged higher, to increase skills to focus and makes the whole thing a kind of meditation.”
