This 82mm Tiffen Water White Glass IRND Filter 82mm 4-Stopis a neutral density filter with a 16x filter factor that provides a 4-stop exposure reduction. Its 1.2 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By increasing your aperture or slowing your exposure time, you are able to control depth of field and convey movement more easily. Neutral density filters are intended to not affect the coloration of the image and are ideal for pairing with other filters.

The design of this filter has been optimized for use with digital sensors and to promote nearly flat attenuation of visible light and infrared light. Due to imaging sensors' greater susceptibility to infrared light, compared to traditional film, color casts can occur when photographing darker subjects that require increased exposure times.

This filter is noncoated, is constructed from Water White glass for increased clarity, and features an aluminum-alloy filter ring for durability while remaining lightweight. It is made using ColorCore technology, a process that involves laminating the filter substrate between two pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch.
