UV filters are special coatings used in photography and videography to block harmful ultraviolet (UV) light. They help protect camera lenses from scratches and dust while also reducing the haziness that UV light can cause in images. By using a UV filter, photographers can achieve clearer and sharper pictures, especially in outdoor settings where sunlight is strong. In addition to their protective qualities, UV filters can enhance the overall quality of photos. They allow visible light to pass through while filtering out UV rays, which can lead to better color accuracy and contrast. Many photographers consider UV filters an essential accessory for their cameras to ensure the best possible results.
