Schneider has pushed ND filter technology forward with their line of Full Spectrum ND filters. As the name implies, these ND filters take into account the full spectrum of possible IR contamination. Previously, ND filters addressed the IR contamination that sensors captured in certain shooting conditions, but with a shift in dark colors. Full Spectrum ND filters are designed to complement refinements in sensor manufacturing that help address IR contamination.

With today's modern camera sensors being so sensitive to light, we often have to use ND filters. Traditional ND filters are designed to neutrally reduce all light, but will not adequately cut the infrared or far red light that causes problems in many cameras.

There are definitely some unique filtration needs that arise from using today's large-sensor cameras. I stopped by Tiffen's NAB booth and talked with Sandie Stern about their new filter offerings, such as their IRND Polarizers.

On November 20, AbelCine held the first event in its new EXPO series: Filters for Digital Cinema. Tiffen, Schneider Optics, and Formatt participated and scores of clients attended or watched via Livestream. One of the more significant discussions was on the topic of IR pollution control.
