The Tiffen Series 9 infrared (IR) neutral density (ND) combination filter helps control colour shift due to IR contamination in digital videography, whether you're using a neutral density filter with an HDSLR or HD camera. The CCD or CMOS sensor in a digital camera is naturally sensitive to infrared contamination, even when the manufacturer attempts to reduce this issue by adding an infrared-absorbing filter over the image sensor. Blacks become magenta and greens become dull brown. Infrared light focuses at a different focal distance than visible light; therefore, your images may appear slightly soft. The more light you cut, the greater the IR contamination; so whether you're reducing light generally or want to create shallow depth of field for a cinematic look, the more IR contamination you'll encounter.

Tiffen has solved this problem by offering its exclusive range of Full Spectrum Water White ND IR filters in limited threaded sizes for HDSLR. Tiffen's IR ND filters don't have a sharp cut-off at infrared wavelengths; therefore, the wide colour gamut that these sensors record is not compromised. The result is vibrant colours without IR contamination, with sharp and clean images that only water white glass can deliver. These filters also provide greater latitude when editing in post-production and are ideal for compressed 8-bit colour.

Water white glass, using Tiffen's ColorCore technology, is characterised by high transmission quality. It also has anti-glare and anti-reflective properties that make it useful in a wide range of applications, including the film industry, shop windows and art exhibitions. The glass is virtually flawless and is increasingly present in digital equipment.


Superior Quality


- High-quality filter to prevent colour shift caused by the sensitivity of current digital sensors
- The biggest Hollywood film studios trust Tiffen filters for their multi-million pound productions. Superior quality and design make Tiffen the go-to choice for filmmakers, professional photographers and even NASA
- Tiffen has also received an Emmy from the Academy of Television Arts and Sciences for its engineering excellence
- Tiffen, a leader in the filter industry, proudly manufactures its filters in the United States


ColorCore Technology


- Tiffen's ColorCore glass is sealed between two sheets of optical glass. This way, Tiffen can better control the different densities of their filters and thus create more precise degrees of filtration. This process allows for greater colour accuracy compared to simply tinted glass which can be subject to variations during the tinting process


Neutral density filters have four main uses



- To enable the use of slow shutter speeds, particularly with high ISOs, to record movement of subjects such as waterfalls, clouds or cars
- To decrease depth of field by allowing the use of wider apertures, which helps separate subjects from their background
- To decrease the effective ISO of high-speed films (above 400 ISO) and allow their use outdoors in bright situations
- To allow cinema and video cameras (which have fixed shutter speeds) to film subjects like snow, sand or other bright scenes that might cause overexposure
