A matte box is a device that attaches to the front of a camera lens in film and video production. It serves several purposes, including:
- Light control: Matte boxes feature adjustable flaps that block light from entering the lens and reduce lens flare, improving image quality.
- Filter holder: Matte boxes often have a filter holder that accepts round filters, such as neutral density filters, which reduce the amount of light entering the lens.
- Sunshade: The matte box acts as a sunshade, protecting the lens from the elements and reducing lens glare.
Matte boxes come in different sizes, materials, and configurations to fit a wide range of cameras and lenses. They range from basic models to more advanced models with multiple filter stages and adjustable flags.
In short, the matte box acts as a barrier between the lens and the elements, providing improved image quality and protection for the lens.
