Simon Buxton of UWUHD and NAD Lembeh has posted a short film combining underwater 4K footage shot with a RED Epic, some clips from Panasonic GH4 with aerials shot with a DJI Phantom 2 with GoPro Hero 3+. The footage was all shot in Tonga and features the humpback whales (Megaptera novaeangliae) which migrate each year from their feeding grounds in the Antarctic to the warm, sheltered waters of Vava’u to mate and calf.
