Offering a 10-stop reduction in exposure, along with infrared attenuating abilities, the Tiffen 49mm XLE Series advantiX IRND 3.0 Filter enables the use of longer exposure times with maintained color fidelity. By darkening the entire scene, this 3.0-density filter allows you to work with wider apertures or longer shutter speeds than normally required, in order to better control depth of field or convey movement more easily.
The IRND design of this filter has been optimized for use with digital sensors, and works to attenuate both visible and infrared light. Digital image sensors are more sensitive to a greater range of light spectra, and as such are prone to color shifts or casts when photographing darker subjects or scenes that require increased exposure times. This filter's unique design helps to suppress false colors for greater neutrality and faithful color reproduction.
This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and mounting to precision metal rings.
