The Matthews 149549 Open End Scrim in 18 by 24 inch size with White 1/4 Stop Silk fabric is a finely tuned lighting control panel used in film, video and photo production. Crafted with a spring‑steel open‑end frame and 3/8 inch mounting pin, it enables precise manipulation of light—reducing intensity subtly, softening direct illumination, and maintaining natural ambient bounce. Suited for tight rigs or specific light modification tasks, this scrim delivers professional durability and rigging convenience while keeping exposure changes minimal. Key Features: 18 by 24 inch dimensional frame for targeted light control: This size gives you a workable footprint to adjust, soften or reduce light on specific areas without dominating larger sets. White 1/4 Stop Silk fabric for subtle light reduction: The ‘1/4 Stop’ designation means light is slightly attenuated (about 0.6 stops) while preserving much of the brightness and still providing ambient bounce, great for when you want softness without heavy loss. Open‑end frame design for edge‑free diffusion or fill: The open side of the frame allows the fabric to hang without an obvious rigid edge, enabling smooth falloff and blending of light rather than a hard cutoff. Spring steel frame with 3/8 inch pin and C‑stand support built‑in: The frame is rugged but light, fitted with a standard grip pin for mounting on C‑stands or grip heads, and includes a support bracket so it can be hung off a stand handle when not in use, simplifying location workflows.
