How is the ocean photographed?

The filming of this film has been supported by many public and private partners (including the state, local governments, enterprises, foundations and so on). ).

In order to explore the theme of marine biodiversity, jacques perrin and Jacques Crouzeau hope to bring the audience closer to the underwater world. This needs to leave the audience with the speed and vitality of the marine world through the screen. To this end, they bravely faced the real technical challenges: "swimming in goldfish foraging at the speed of 10 nautical miles per hour, following the crazy running dolphin team and dancing with the great white shark." 14 French, Japanese and Swedish photographers went to various sea areas in the world for five years. 12 the film crew took a small motorboat to fight the waves and storms. At a cost of 50 million euros, the bold innovation in the shooting process is eye-catching. In order to photograph whales without disturbing them, the crew installed a crane on the boat and fixed the camera on the crane's cantilever: it was called Tethys device, designed by jacques perrin and photographer Alexandre Bügel. The technical means used in the shooting is unique: when the sperm whale jumps out of the water, the miniature electric remote control helicopter (Birdyfly) can quietly approach the shooting; The "underwater aerial camera" can capture the backstroke of seals, sea lions and water. The key to realize these innovative shooting is the digital camera installed on the fast torpedo, which is towed at the stern with an optical fiber. When the ship moves forward, the camera on the torpedo can photograph the marine animals in front at the stern.

Jacques Crouzeau praised: "In Iles Cocos Islands, in the vast waters of Costa Rica, you can see all kinds of busy fish, sharks, rays, turtles and marine mammals as long as you put your head into the water." On Coburg Island in the northern Arctic Ocean, polar bears, walruses and seals are still the owners of the island and are not disturbed. At the westernmost tip of the Galapagos Islands, those eagles, iguanas, sea lions and cormorants have no qualms about taking a nap a few meters away from the film crew. In transkei (South Africa), flocks of seabirds dive into the water, diving into the sea ten meters deep to catch sardines.
