Light Control for Photo and Video

The Rosco Cinegel N.3 is a neutral density filter that cuts light intensity by a single stop. It measures 20 by 24 inches and transmits 50 percent of incoming light. Photographers and videographers use it to balance exposure between bright exteriors and darker interiors.

Use Cases and Limitations

The filter suits professionals who need precise exposure control without shifting color balance. It also lowers daylight to match 3200 K tungsten sources for mixed-lighting scenes. Buyers who need more than one stop of reduction or a different sheet size should look at other options.

Key Specification

The filter provides a 1.0 stop reduction with a 0.3 density rating across the full 20x24 inch surface. This exact density determines whether the filter matches the exposure adjustment required for a specific shoot.

Questions about this item

How much light does the 0.3 density filter transmit during a full day of shooting?

The filter transmits 50% of incoming light, giving a consistent 1.0 stop reduction across the 20x24" surface.

Does the gel produce noticeable heat or colour shift after hours under hot studio lamps?

It is engineered for even spectral reduction, so colour accuracy holds and the material tolerates continuous professional use without warping.

What mounting gear do I need to hold the 20x24" sheet in front of a light source?

A standard 57-inch wide frame, C-stand with grip head, or Matthews-style butterfly kit will secure the filter for overhead or stand-mounted setups.
