4.5" IRND Filter - Water White Density:1.5 They can be rotated inPairing infrared attenuation with solid neutral density, the 4. 5" Round Water White Glass IRND Filter from Tiffen is a versatile solution to reduce exposure values and achieve neutral color. The neutral density portion of the filter offers a 4 stop exposure reduction for working with longer shutter speeds or wider aperture settings. The infrared portion attenuates infrared wavelengths above 700nm to benefit working with CCD and CMOS sensors under
