A reflector is a device or surface that bounces back light or other forms of energy. Commonly made from materials like glass or metal, reflectors are used in various applications, including lighting, photography, and safety devices. For example, in a car, a reflector helps enhance visibility by reflecting headlights, making the vehicle more noticeable at night. In photography, reflectors are used to redirect natural or artificial light onto a subject, improving the quality of the image. They come in different colors and sizes, allowing photographers to manipulate light effectively. Reflectors are essential tools for both amateur and professional photographers, enhancing their creative possibilities.
