The Matthews 319613 12x12 foot overhead fabric is a professional lighting diffusion panel designed for large area coverage in studio or location shoots. Made from white 1/4 stop silk material, it softens and diffuses direct light while retaining ample brightness. The fabric includes reinforced webbing edges and grommets for secure rigging. It is sized to fit standard 12x12 foot butterfly or overhead frames, ideal for controlling harsh sunlight or strong artificial lighting and creating even flattering illumination across wide scenes. Key Features: Large 12x12 Foot Size for Broad Coverage: Covers a wide area to diffuse large lighting sources or illuminate wide subjects and sets evenly. 1/4 Stop White Silk Material: Slightly reduces light intensity while maintaining color neutrality, providing soft ambient light without significant loss of brightness. Softens Harsh Light Sources: Mitigates hard shadows and bright highlights from strong sun or studio lamps, resulting in more even and flattering illumination. Ambient Light Bounce: White silk surface reflects and scatters light to maintain natural look while softening direct light. Reinforced Edges with Grommets: Strong webbing and grommets around the perimeter allow secure attachment to overhead frames or rigs, suitable for repeated use on set.
