Haida NanoPro MC UV/IR Cut Filter Waterproof Scratch Resistant Nano Coating Optical Glass SLR Photographic Filter (62mm) - 4222-62

• The Haida NanoPro UV/IR Cut 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 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. When the Haida 62mm NanoPro MC UV/IR Cut Filter is applied, ultraviolet light waves are blocked at 390 nanometers along with infrared light waves at 750 nanometers, helping to ensure that light falling on a digital camera sensor is limited to the visible spectrum. When combined with a wide-angle lens, lower-frequency wavelengths of visible light associated with yellow, orange, and red colors passing through the filter and along that lens type's curved edges can be impeded in a significantly greater degree than higher-frequency wavelengths of visible light associated with blue and violet colors. To avoid color shifts using this filter, it is recommended not to be used with lenses that are intended to provide an angle of view greater than 60°.
