Germany’s Robert Koch, an electronic music artist, has filmed the video for his track Dark Waves (featuring Delhia de France) entirely on an iPhone 6s, as shared by Apple SVP Phil Schiller on Twitter.

Check out the impressive footage below:

The video is from artist’s new album Hypermoment, released back on November 6, 2015. As you can see, the iPhone 6s used in the ocean to film various scenes both in and out of the water.

Director Sven Dreesbach told Mashable “The entire footage in Dark Waves was captured during the course of three early mornings, when the water was just the glassiest and best to surf in. Every session took maybe 60 minutes to a couple of hours each.”

As for equipment used? Dreesbach used a Watershot housing case, Beastgrip system and iOS app Filmic Pro.
