Product Highlights
  • Enables Use of ND Without IR Pollution
  • Maintains Color Fidelity
  • Ideal for HD Cameras
  • ColorCore Water White Glass

The Tiffen 4 x 5.65" Full Spectrum IRND 0.9 Filter is a combination of both an infrared control filter and a 0.9 neutral density filter. An IRND is ideal for HD cameras, which have greater low-light sensitivity and, subsequently, an increased susceptibility to IR contamination. When using a standard neutral density filter to counter the increased light sensitivity afforded by the HD sensor, the effects of infrared pollution become more apparent. This filter combines an ND filter with a comparable IR control filter to eliminate the spill of infrared light reaching the sensor while still maintaining the extra exposure benefits of a neutral density filter.

This filter is constructed from Water White glass and is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 4 x 5.65" / 101.6 x 143.5mm.

Infrared control filter helps to block infrared pollution from affecting the color fidelity of imagery; this enables a wider color gamut and truer colors, especially noticeable in the darker regions of the image.
0.9 neutral density filter provides a 3 stop exposure reduction.
Water White optical glass for excellent clarity.

      Comments about Tiffen 4 x 5.65" Full Spectrum IRND 0.9 Filter:

      These filters get the job done and prevent any IR contamination. There is a slight shift in color which can easily be corrected in post or in-camera. Many cinematographers use this.

      This will not work on the Red Camera sensors - they need a hot mirror as well. So keep that in mind. I hear these range of IR filters are the best choice for Alexa, as these filters do the least amount of damage to the skin tones.
