Lens and light filters are accessories used to enhance underwater photography by modifying the light and color that reaches the camera sensor. Red filters, for example, help restore natural colors lost due to the absorption of red wavelengths in water, while UV filters protect the lens from scratches and other damage. Light filters can also help reduce glare and improve image quality. Proper cleaning and maintenance of these filters are essential to prevent image distortion and ensure clear, high-quality underwater photos and videos.
