Underwater filming involves capturing video or images beneath the surface of water bodies, such as oceans, lakes, and rivers. This technique is commonly used in documentaries, movies, and scientific research to showcase marine life, underwater landscapes, and aquatic activities. Specialized equipment, like waterproof cameras and housing, is essential for protecting gear from water damage. To achieve high-quality underwater footage, filmmakers often use additional tools like underwater lights and stabilizers. The process requires careful planning, including understanding water conditions and marine environments. Notable examples of underwater filming can be seen in works by Jacques Cousteau and in films like Finding Nemo.
