Definition & Meaning of "matte box"

What is a "matte box"?

A matte box is an accessory used in filmmaking and photography to control light and reduce lens flare. It attaches to the front of a camera lens and includes adjustable flaps that can block stray light from hitting the lens. The matte box often holds filters, such as neutral density or color filters, allowing for precise control over exposure and color effects. It helps achieve clearer, more focused images by managing light and glare.
