The Tokina PRO IRND filter is a revolutionary filter that stabilizes the transmittance of color throughout the visible spectrum. There are generally two types of IRND filter manufacturing processes currently in the market today. One type cuts the near infrared from a particular wavelength and the other controls rather than cuts the infrared up to 1200 nm. The Tokina PRO IRND filter is of the latter category, using suppression rather than cutting to eliminate infrared pollution. Even though both methods can be equally effective, the former type of cutting is often prone to producing unwanted color shifts. The round PRO IRND filter has an ND vapor deposition coating on both sides of the glass creating a high-precision, truly neutral filter.

• No extra white balance adjustments
• No IR pollution
• No color shift
• No color corrections

Q: 4. I have a mirrorless camera that I had converted for IR photography; regular ND filter do not have any effects on exposure; I want to shoot IR with long exposure, will this NiSi IRND do the job?

A: No, the NiSi 82mm PRO Nano IRND 3.0 Filter (10-Stop) would not be compatible for your usage needs. It does the opposite of what you are looking for; it is designed to block IR to the extent that there will not be infrared pollution when taking a long exposure. As an alternative, the filters in the NiSi Swift FS ND Filter Kit (82mm), B&H # NIRFSNDSWK82, are designed to pass all wavelengths of light evenly, so this would also be an alternative for your usage needs. Also, as standard neutral density filters pass along infrared light unless it specifically indicates it has IR reduction, a filter such as the Hoya ProND EX 1000 Filter (82mm, 10-Stop), B&H # HOPNDEX1T82, should also work for your usage needs. https://bhpho.to/3ieQ30o https://bhpho.to/3LZm8bn
