They are often waterproof and can withstand high pressure, making them suitable for activities like snorkeling, diving, and marine research. Many underwater cameras come with features such as wide-angle lenses and built-in flash to enhance visibility in low-light conditions. These cameras can vary in complexity, from simple point-and-shoot models to advanced DSLR systems with underwater housings. Some are even equipped with Wi-Fi capabilities, allowing users to share their underwater adventures instantly. Overall, underwater cameras enable enthusiasts to explore and document the beauty of aquatic environments.
