4 x 5.650" IRND Digital Diffusion/FX

Combining three distinct effects within a single filter, the 4 x 5.65" IRND Digital Diffusion/FX Filter offers a 3 stop exposure reduction, attenuates infrared wavelengths, and slightly softens skin details and textured backgrounds. Intended for use with high definition video capture with CMOS and CCD sensors, this filter compensates for the extended red sensitivity of these sensor designs in order to produce cleaner, more accurate colors and also takes the over-sharpened "digital edge" off for a smoother image quality. The filter is constructed from water white optical glass for maintained clarity and measures 4 x 5.65" / 101.6 x 143.5mm to pair well with lightweight or clip-on matte boxes. Alleviating the need to use multiple filters at once, this filter combines three distinct effects to reduce the number of filter surfaces in use. Infrared attenuating design is proportionate to the neutral density value, and helps to ensure clean, accurate colors and true blacks. Digital Diffusion/FX effect softens skin details and textured backgrounds for a smoother image quality. No. 1/2 diffusion strength provides the least amount of softening, which is less than the 1 strength. Well-suited to high definition video applications where an over-sharpened "digital look" is undesirable. Diffusion design remains invisible when lens is stopped down for greater versatility in exposure control. Constructed from water white optical glass for maintained image quality.
