This is the 4.5" Round Combination Infrared 85 Neutral Density 2.1 (ND) Filter from Tiffen. What do you do when you must take some photos outdoors and all you have left is tungsten film? Using tungsten film in daylight will produce a bluish cast in the photograph. The 85 series of filters will "bring back", i.e. color balance the tones in your images. This yellow filter is used to correct differences in color temperature between the recording medium (film/video) and the light source.

Color shift is a critical factor in digital photography especially when dealing with the infrared spectrum - and even more important when shooting with HD technology.  Unlike traditional film cameras, CCD or CMOS sensors of a digital camera are, by nature, susceptible to infrared contamination. Manufacturers try to avoid this problem by incorporating 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. Despite these precautions, some infrared wavelengths pass through resulting in contamination of the image. This filter delivers the best of both worlds - color balance as well as minimizing infrared contamination.

A neutral density filter has several uses and offers the possibility to achieve otherwise unachievable results. It enables the shooter to adjust exposure without affecting color balance. An ND filter appears gray and reduces the amount of light reaching either the sensor of a digital camera or the film plane of a traditional film camera.

Neutral density filters are used to create some unusual special effects such as capturing the "blur" of the rippling water of a waterfall or the swirling effect of city traffic. Since it allows the use of slower shutter speeds in bright light, it becomes possible to create these special effects that would normally not be possible to capture without the filter. And, since it can also help to control your depth of field, it permits you to shoot at wider apertures. Ultimately, its value is in helping to prevent bright, overly washed out images shot in bright light.

A 2.1 (7 stop) Neutral Density filter causes such a distinction between fore/background that your subject will become completely isolated from the rest of the image. Water will appear to be flowing at a rapid rate even though in reality, it was just a trickle. Using this filter on a very bright beach with a high ISO will prevent the shot from being completely washed out and overexposed.

Water White glass, using Tiffen’s ColorCore technology, is characterized by a high transmission quality. Typically, it will transmit 98-99% of the light. It also features an anti-glare and anti-reflective quality that makes it useful in a wide range of uses including the movie theater industry, store and art displays. The glass is virtually defect-free and is becoming more and more prevalent in digital equipment.

Neutral Density Filters Have Four Uses
To enable slow shutter speeds to be used, especially with high speed ISOs, to record movement in subjects such as waterfalls, clouds, or cars
To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background
To decrease the effective ISO of high speed film (above ISO 400) and allow it to be used outdoors in bright situations
To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which could cause overexposure

Superior Quality

Tiffen's ColorCore glass is sealed between two optical glass sheets. In this way, Tiffen can better control the various densities of their filters and thereby create more exact degrees of filtration. This process makes for greater accuracy of color as opposed to glass that is simply dyed and become subject to deviation during the dye process
Top Hollywood motion picture studios rely on Tiffen filters for their multimillion-dollar productions Superior quality and design make Tiffen the overwhelming choice of movie makers, professional photographers and even NASA
Tiffen has also been awarded an Emmy, from the Academy of Television Arts and Sciences, for its engineering excellence
Tiffen, a leader in the filter industry, proudly makes its filters in the USA and backs up its products with a solid 10-year warranty
