Camera filters are special accessories that attach to the front of a camera lens to modify the light entering the camera. They can enhance colors, reduce glare, or create artistic effects. Common types include polarizing filters, which help reduce reflections and improve contrast, and neutral density filters, which allow for longer exposure times without overexposing the image. Using camera filters can significantly improve the quality of photographs. For example, a UV filter can protect the lens from scratches while also reducing ultraviolet light, which can cause haziness in images. Overall, filters are valuable tools for photographers looking to achieve specific visual effects.
