The Tiffen 4 x 4" 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.

question
Will 680nm to 800nm work well on a Blackmagic Pocket Cinema Camera? I used a 750nm IR cut and it still produced a very red image. Possibly thinking the BMPCC is more sensitive to light on the lower end (680nm) so was thinking about checking this filter out. Any info?
It would seem no one else has tried this idea. It sounds as though it might work. Try it and let us know what happens.

I have 4x4 plain ND filters by adding this IR glass on matte box will my plain ND filters work like IRND filters, or I need to buy all IRND filters to block Infrared?
Yes, that combo will give you an IRND effect.
