Brazilian adventure photographer Murilo Vargas (@100limitefilmes) shares adrenaline for a living. “Rock climbing got me into photography, as I always wanted to capture the essence and beauty of the sport. When a friend gave me my first camera back in 2004, I became instantly fascinated with capturing my altitude adventures on film, and adventure photography became my obsession,” says the 34-year-old Rio de Janeiro resident. Murilo has found that capturing athletes at daredevil heights can be just as intense as performing the sport. He recalls a time he photographed a friend highlining — traversing an inch-wide (2.5 cm) nylon line — over Mina Gerais’ Tabuleiro waterfall without any safety ropes. “He was trying to keep his balance. My hands were shaking and sweating, my heart was pulsing and I was so scared that I couldn't concentrate to capture the best angle. Honestly, I was really happy when it was over and he was safe!” Photo by @100limitefilmes
