Schneider 77mm True-Cut 750 IR Filter

The Schneider 77mm True-Cut 750 IR Filter is an infrared control filter that is designed for digital cinematography. While recording video with a CCD or CMOS camera, multi-stop neutral-density filters are used to maintain proper exposure by compensating for increased light levels when widening the camera lens's iris to obtain a narrower depth of field. As the increased amount of light passes through multi-stop neutral-density filtration, visible light is progressively blocked, while infrared light is allowed to pass through. As the proportion of infrared light that reaches the sensor of a digital cinema camera becomes greater, the results can show unwanted color shifts, particularly in dark areas of the frame such as shadows where the appearance of black is dominant.
