Tiffen 4 x 5.65" T1 IR Filter

The Tiffen 4 x 5.65" T1 IR Filter is a near-infrared to infrared control filter that is designed for digital cinematography. Many digital motion-picture cameras are designed to maximize their ability to capture red hues, and in that process near-infrared or infrared contamination may occur. If the proportion of near-infrared or infrared light that reaches the sensor of a digital cinematography camera becomes too great, the results can show unwanted color shifts, particularly in dark areas of the frame such as shadows where the appearance of black is dominant.
