Rosco Cinegel #3421 濾色片 20” x 24” 片 (BlackScrim)

Fits perfectly over my LED panel and dropped the brightness just as needed for a more natural-looking indoor scene. The perforations are so fine you barely notice them in the final shot.

Taped a couple sheets to my studio window to cut down the harsh afternoon sun—dropped the light level exactly two stops without shifting the color temperature at all. The perforation pattern is fine enough that you can't even see it from a few feet away.

Cut perfectly to fit my window frame, and the black-on-both-sides perforation really does knock down the light exactly two stops without changing color. I've used it for two shoots already and the sheets are holding up well to taping and re-taping.
