In terms of the shooting technology of "Blue Planet II", the machine has changed from a 16mm film camera to a 6K high-definition digital video camera, and the captured images can be clearly displayed even on the IMAX screen. At the same time, the BBC has also rented several deep-sea submersibles, which can spend more than ten hours on the seabed at a depth of 1,000 meters. The underwater shooting time reaches more than 6000 hours

Honeyburn said that the biggest technological breakthrough in underwater shooting is the improvement of "respiratory diving technology". Compared with the traditional "scuba" diving technology, this technology allows divers to stay underwater for up to 4 to 5 hours without generating bubbles and noise, and can approach them in a way that is fully acceptable to marine life and observe them closely. Their personality and wisdom

The film’s photography team used a variety of cameras, such as low-light cameras, probe cameras, suction cup cameras, and high-speed cameras. Under this shooting technique, the audience can see the "Fluorescent Coast" in the movie " Life of Pi ". Special effects are used in the movie, but this time it is a real shot. Using a high-sensitivity low-light camera, we captured the glowing scene of certain algae in the sea when manta rays swam. When shooting underwater, the photographer is in a dark environment and can't see anything with the naked eye
.
The high-sensitivity camera made it possible to shoot creatures in the deep sea with very little light. The filming team used this equipment to successfully capture the hunting behavior of the American red squid in the 800-meter deep sea.
The team also "homemade" some new shooting equipment. For example, the high-definition giant hemispherical camera they made can divide the shooting picture into two with the sea level as the center line, allowing the audience to see both the water and the underwater world at the same time. When shooting the walrus on the iceberg, the audience can see the huge underwater iceberg at the same time, and get a clearer and three-dimensional understanding of their living environment.
In order to photograph marine life such as tuna and dolphins that march quickly, the team invented a drag camera, which can be bound to a speedboat to quickly follow the subject. In addition, the team has also developed a probe camera, which can go deep into the corners and crevices of coral reefs to take pictures of the life world of tiny creatures
