Underwater photography and videography involve capturing images and videos beneath the water's surface, showcasing the beauty of marine life, underwater landscapes, and divers in action. This type of photography requires specialized equipment, such as waterproof cameras and housings, as well as lighting tools to counteract the loss of color and light underwater. It's a unique and challenging field, demanding knowledge of diving, marine environments, and the technical aspects of photography or videography to produce high-quality, clear, and vibrant images or footage.
