SKU CH-C13H-8WEX8

A 20x24 inch neutral-density filter cuts light by three stops with 12 percent transmission while preserving colour accuracy

  • Precise colour accuracy with true-to-life rendering for professional photography and videography
  • Three-stop neutral density reduces light intensity by three stops without colour shift
  • Superior heat resistance withstands high studio-light temperatures during extended shoots
  • Enhanced durability resists tearing and fading for long-lasting reliability in demanding use
  • Optically clear deep-dyed material delivers 12% transmission for consistent light quality

Professional Light Control

The Rosco Cinegel N.9 is a 20x24 inch neutral density lighting filter designed for photographers and videographers who require precise exposure management. It reduces light intensity by three stops with a transmission rate of 12 percent, allowing control over bright sources without shifting color balance.

Thermal Stability

Constructed with deep-dyed materials, the filter withstands high temperatures from studio fixtures during extended shoots. Its superior heat resistance maintains optical clarity and structural integrity, preventing warping or degradation that would compromise consistent light quality.

Large-Format Integration

The 20 by 24 inch sheet dimensions suit window applications for balancing exterior daylight with interior 3200 Degree K lighting. Extra-wide 57 inch roll availability supports broader coverage needs, while the robust construction resists tearing for reliable mounting in demanding production environments.

Questions about this item

How do I install the 20x24 inch sheet and what step causes the most problems?

Cut the 20 by 24 inch sheet to fit your frame or window, then tape or clamp it flat. The step most people miss is cleaning the surface first — dust or oil creates bubbles and hot spots that ruin the optical clarity.

What maintenance or replacement will the Rosco Cinegel N.9 need after repeated studio use?

The deep-dyed polyester resists fading, but extended heat from high-output lights eventually embrittles the material. Plan to replace the sheet when you see yellowing, cracking or a measurable drop from the 12 percent transmission spec.

What limit appears first when the filter runs under continuous hot lights?

Heat resistance is rated as superior, yet the base polyester softens well below the 3200 Kelvin source temperature. In practice the sheet warps or brittles before the neutral density or color accuracy degrades, so that thermal limit arrives first.
