Swimming with Humpback Whale, filmed by the Japanese senior photographer Hiroyuki Nakagawasai, as commissioned by Delta vividly and realistically captured how humpback whales raise their next generation with the 8K ultra-high-definition technology. It aims to make people recognize their figures, living patterns, and contribution to carbon sequestration, and take action for marine conservation together. The film won the gold award in the short-length documentary film category at the WorldFest-Houston in 2022.
