Neutral Density Filter Kit
Includes Carry & Storage
The Tiffen 77mm Indie Pro Infrared Neutral Density Kit is designed to correct color shift from infrared contamination. Since the advent of digital cameras to the professional Motion Picture industry, the infrared light spectrum has changed the formal quality of the final image creating, in some instances, very notable color shifts. As High Definition Cameras begin to replace film as the medium of choice for more productions, the sensitivity of the imaging sensors to IR has become a challenge. This is particularly evident when using standard neutral density filters that absorb visible light but pass infrared.
Unlike many photographic films, the CCD or CMOS of a digital camera is inherently susceptible to infrared contamination, even when the manufacturer attempts to reduce this problem by adding an infrared absorbing filter on top of the image sensor. Because these filters do not have a sharp cutoff at the infrared wavelengths there has to be a compromise in order not to exclude visible red wavelengths. This results in some infrared wavelengths being allowed to pass. While minor infrared contamination does not normally cause much of a problem for visible images, when using conventional neutral density filters especially denser grades, this issue is multiplied by the filter factor.
Tiffen has now addressed this problem with the introduction of its exclusive line of IR ND series filters. Using Tiffen's exclusive ColorCore filter technology, Tiffen engineers have been able to eliminate Infrared bleed above 700nm. This is particularly important as it now allows for the use of the denser grades of Neutral Density filters needed for these light sensitive cameras while, at the same time, maintaining complete color balance.
The Tiffen IR ND series is produced using Water White glass. As with all Tiffen filters, IR ND filters are ground and polished to provide the greatest level of flatness and parallelism. This, together with their exclusive ColorCore technology, ensures the highest level of optical quality.
The Tiffen 77mm Indie Pro Infrared Neutral Density Kit features the Tiffen IR ND filters in ND.3, ND.6, ND.9, ND1.2, ND1.5, ND1.8 and ND2.1.
