When filmmaker Bryan Smith calls this “the ultimate full moon shot,” he’s not boasting.
If you’re going to stage a shot of a guy walking a highline on Yosemite’s Cathedral Peak, you figure out the perfect time: In this case, a full moon rising as the sun sets.
To get the shot, filmmaker Mikey Schaefer (the voice you hear on the radio in the clip) filmed Dean Potter with an 800mm lens and double lens converter from more than a mile away, making the moon appear huge behind Potter as he solos up to the slackline and walks across. The shot was captured during the 2011 filming of the National Geographic Channel show The Man Who Can Fly, which featured Potter wingsuiting, BASE jumping, and free soloing the upper 600 feet of Freerider (5.12d) on El Cap. The show airs again January 11.
