138mm Round Water White Glass IRND Neutral Density Five years ago Tiffen respondedPairing infrared attenuation with solid neutral density, the 138mm Round Water White Glass IRND is a versatile solution to reduce exposure values and achieve neutral color. The neutral density portion of the filter offers a 3 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 difficult lighting
