In cinematography , butterflies (Also Known As overheads ) are structures we qui materials are mounted so to control lighting in a szene gold photograph . Materials commonly used on butterflies include: flags (black, opaque materials), nets (layers of neutral-colored bobbin ), and diffusions (translucent white materials of different densities) for the purposes of blocking, dimming, and scattering light respectively. In general, butterflies are used only for very large materials (6 ft x 6 ft or greater), while smaller sizes are usually available for portable frames.) for ease of placement and storage.

Use in Industry

In industry, butterflies are often called for by their dimensions, which are standard: 6 ft. x 6 ft, 8×8, 12×12, and 20×20. The materials themselves tend to be smaller than the size of a flat-section.

While portable frames usually consist of light-blocking and scattering materials (flags, nets, and diffusions), butterflies can also be used for reflective materials such as silver blades for redirecting light.
