When Hamburg, Germany-based photographer Florian Bison first saw a video of parkour, he was mesmerized by the concept and curious as to how he could integrate it into a photography project. That’s when he came up with the Double Gravity series, a mixture of real and parkour/camera created gravity. The video above offers a behind-the-scenes look at how he created the final product, which was shot using a Nikon D700 with a Nikkor 24-70mm F/2.8 lens and a Pocket Wizard triggered Profoto B2 with two Profoto heads.
