The Tiffen 4 x 5.65" ND 0.9 Filter is a neutral density filter that reduces exposure by 3 stops. This 0.9 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing down your exposure time or increasing your aperture, you can control depth of field and express movement more easily. Neutral density filters do not affect the colouration of the image and are ideal for pairing with other filters.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and polishing it to a tolerance of 1/10,000th of an inch. This filter measures 4 x 5.65" / 101.6 x 143.5 mm.
