Extreme photos at extreme heights

For seven years, Emily Ibarra has traveled the world photographing the death-defying adventures of professional parkour and freerunning athletes. Captured at sites ranging from the Grand Canyon to the Far East, her photos reveal their fearless exploits as they scale skyscrapers, fly across rooftops, and banish fear in precarious poses. Emily loves her job. “It’s exciting. It’s terrifying, and it’s dangerous, and I get to capture that,” she gushes.
