The 4 x 5.65" PolarPro ND Filter 4x5.65 3-Stopfrom PolarPro ND Filter 4x5.65 3-Stopis a 3-stop neutral density filter designed to fit standard matte boxes. It features multicoating for optimal light transmission, plus resistance coating to protect it from scratches, oil, and water. Its lightweight construction makes it ideal for use with gimbals and handheld rigs. It has a protective CNC-machined aluminum frame for easy handling, and the frame has the filter description engraved on it for clarity.

Increasing neutral density offers finer control in available shutter speeds or aperture settings for both still and video applications. Using a longer shutter speed makes it possible to increase blur to convey a sense of movement, or to dial in a video camera frame rate. Increased density also makes it possible to shoot using wider lens apertures, helping to isolate a subject from the background. This level of image control can help to create more cinematic effects in bright light.
