Don’t forget to breathe while watching this. Free diver Guillaume Néry blends the lines between ocean and space in this short film of him swimming in surreal seascapes around the world. Néry dives and swims beneath ice sheets, walks the ocean floor with spearfishermen, and, for the truly mindblowing finale, swims with whales in what must have been a nearly heartstopping moment of beauty for the swimmer and the filmers. Speaking of, this short was shot by Julie Gautier, Néry’s wife, who also held her breath while filming. What a badass. Seriously though, breathe.
