Why the new ocean series looks intentionally blurry

Viewers may wonder if their eyes are playing tricks on them when they watch the new nature series. The water looks cloudy. Boats and buoys are visible in the background. The image is not perfectly sharp. This is not a mistake. It is a deliberate choice by the creators of Blue Planet III, which airs on BBC1 and iPlayer starting Sunday, November 1.

The main claim from the production team is that this rougher look proves the footage is authentic. Artificial intelligence is getting better at making fake videos, so the team wanted to avoid the overly clean look that might suggest computer generation. Executive producer Elizabeth White explained that the technology makes them want to be more authentic. She noted that the animals in the deep ocean are likely more remarkable than what AI could imagine, and the footage is completely real.

In the past, editors would often cut out scenes with plankton in the water. They might have framed out a boat or rejected a shot because the conditions were poor. Now, those details remain in the final cut. White said the team is really leaning into that authenticity. She expects the show to use even murkier and less polished imagery in the future as AI technology grows.

Jack Bootle, the BBC head of specialist factual commissioning, made a specific promise to journalists at a press screening. He stated that no generative AI was used in the series. He emphasized that not a single frame was created by a computer, and it is all real photography. He described the current time as a golden age of natural history making, where viewers might feel they have seen everything before. However, he said this new series is bursting with novel behavior.

The show features several new animal sightings. Dolphins use sea sponges to block holes in coral and trap fish. This behavior was recorded with underwater CCTV developed by the program's producer and director, Yoland Bosiger. Other scenes show a grouper communicating with another species of fish. There are also 200,000 crabs lining up in formation to feed, and sea urchins using shells as sun hats.

Filming took four years across five oceans. The team built new tools to capture the action. They created a mini-dome camera to follow an octopus and a deep-sea selfie stick. Camera operators wore leg-mounted scooters to get immersive diving footage. Lasers were used to film animals in the deep sea. The series also examines threats to the ocean, such as warmer seas killing sea anemones where clownfish live. It continues the plastics theme from the second series by looking at pollutants and forever chemicals.

David Attenborough, who is 100 years old, narrates the series. Bosiger said he was very much involved and made changes to the scripts. White added that he has not lost his curiosity and is still excited when shown new footage. When asked about the BBC's cost-cutting drive, White said she could not comment on the reputation impact. However, she noted that the series saved money by using more local crews on location than earlier productions.
