Marcio Cardoso walks across a thin rope perched high above the breathtaking landscape of Rio De Janeiro. He was part of a group that included thrillseekers Ighor Pereira and Mitsu Kawaguchi. Their destination, the top of Morro do Cantagalo city, took them about four hours to reach. Shot by Brazilian professional outdoor photographer Bruno Graciano, 28, the photograph also provides an extraordinary view of Rodrigo de Freitas lagoon.
