A camera filter is a special accessory that you attach to the front of your camera lens to change how the light enters the camera. Filters can enhance colors, reduce glare, or create artistic effects in your photos. For example, a polarizing filter helps to make the sky look bluer and reduces reflections on water, making your images more vibrant. There are many types of filters available, each serving a different purpose. A neutral density filter allows you to take long exposure shots even in bright sunlight, while a UV filter can protect your lens from scratches and dust. Using filters can greatly improve the quality of your photography.
