Tiffen 6.6x6.6" WW IRND 0.9 Filter

Professional IR and Exposure Control

The Tiffen 6.6x6.6" WW IRND 0.9 Filter is a high-performance solution for cinematographers using modern digital sensors. As HD cameras have become more sensitive to low light, they have also become increasingly susceptible to infrared (IR) contamination. When using standard ND filters, this IR pollution often results in unwanted color shifts, particularly in dark shadows. This filter integrates a 0.9 neutral density (3 stops) with a specialized IR control layer to ensure your images remain crisp and color-accurate.

Advanced ColorCore Technology

Each filter is manufactured using Tiffen's proprietary ColorCore technology. This process involves laminating the filter material between two pieces of Water White optical glass. The assembly is then ground flat to a tolerance of 1/10,000th of an inch. This ensures exceptional clarity and consistency across the entire surface of the 6.6x6.6" filter, making it ideal for high-resolution cinema production.

Key Features for Cinematography

• Infrared Suppression: Blocks IR light from reaching the sensor, preventing magenta shifts and preserving a wide color gamut.
• Neutral Density 0.9: Provides a 3-stop light reduction, allowing for wider apertures or slower shutter speeds in bright conditions.
• Water White Glass: Offers superior optical purity compared to standard green-tinted glass.
• Professional Format: The 6.6x6.6" size is compatible with industry-standard matte boxes for high-end film and video work.
