Underwater filmmaking involves capturing video and images beneath the surface of water bodies, such as oceans, lakes, and rivers. This specialized field requires unique equipment, including waterproof cameras and housings, to protect gear from water damage. Filmmakers often use techniques like scuba diving or snorkeling to reach their subjects, which can include marine life, underwater landscapes, and human activities. The process also involves understanding underwater lighting and currents, as visibility can be limited. Filmmakers may collaborate with marine biologists to accurately portray aquatic ecosystems. Notable examples of underwater filmmaking include documentaries by Jacques Cousteau and films like Blue Planet.
