Primarily shot using two Red Epic cameras, which were stripped down to minimize weight, and a collection of smaller cameras, including a Canon EOS-1D C , Sony NEX-FS700, GoPros and even cellphones.
Director Jennifer Peedom also operated a camera. The cinematographers additionally trained Nima and Nawang Sherpa on Sony Handicams and GoPros to film the Icefalls.
The production team shot more than 400 hours of footage.
Much was shot handheld, and Freefly Systems also lent the production a MoVI lightweight stabilization rig that was used in conjunction with the Red Epic for some sweeping shots. Also some aerials from a helicopter were shot 'hanging out an open door'.
