The Rosco Cinegel #3402 Filter in a 20” x 24” sheet is a practical light-modifying tool for photographers and filmmakers who need to control exposure without changing color temperature. This neutral-density filter reduces incident light by one full stop, making it easier to balance ambient light with flash or to shoot with wider apertures in bright conditions.

  • Reduces light by one stop (transmission = 50%) for precise exposure control.
  • Optically clear material helps maintain image sharpness and color neutrality.
  • Convenient 20” x 24” sheet size is suitable for a variety of lighting fixtures and DIY setups.
  • Mired shift is N/A, meaning it does not alter color temperature.

Steven ★★★★★

Cutting this 20x24 sheet was a breeze with a sharp blade, and it mounted perfectly in my matte box. The neutral density is consistent across the whole surface, which saved me from having to tweak exposure in post. Exactly what I needed for outdoor shoots in bright sun.

Mia ★★★★★

Finally got this to dial in my exposure perfectly on a bright day shoot—the 20x24 size was just right for my key light setup. No color shift at all, just clean, even reduction. Exactly what I needed.

Christopher ★★★★★

I was shooting a quick outdoor portrait and this ND sheet knocked my exposure down perfectly without shifting the colors. The 20x24 size gave me plenty of room to cut a custom shape for my light.
