Camera filters are accessories used in photography to modify the light entering the camera lens. They can enhance colors, reduce glare, or create special 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. Filters can be made from glass or resin and are typically mounted on the front of the lens. They are popular among both amateur and professional photographers for their ability to improve image quality and achieve creative results. Using filters can significantly impact the final look of a photograph.
