Tiffen Infrared (IR) Neutral Density (ND .3)
Tiffen Hot Mirror IR Neutral Density Filter - Color shift is a critical factor in digital photography. This color shift is directly affected by the infrared spectrum. Specifically, in high definition photography, the sensitivity of 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 and IR 85ND series filters. 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.
