B+W 112mm UV/IR Cut MRC 486M Filter

The B+W 112mm UV/IR Cut MRC 486M Filter is an ultraviolet and infrared control filter that is useful for digital cinematography as well as still photography. 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 camera being used for digital cinematography 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.
