This is the 4.5″ Round Combination Infrared 85 Neutral Density 1.2 (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 filteris 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 theinfrared spectrum – and even moreimportant when shootingwith 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 incorporatingan 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 reachingeither the sensor of a digital camera or the film plane of a traditional film camera.

Neutral density filtersare used to create some unusual special effects such as capturing the “blur” of the rippling waterofa waterfall or the swirling effect ofcity traffic. Sinceit 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, sinceit 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 1.2 (4 stop) Neutral Density filter is useful when shooting in exceptionally bright light with fast ISOs. At this point, anything passing through the shot begins to slow down to an appreciable degree i.e. running water appears to blur.

Water White glass, using Tiffens 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 In the Box Tiffen 4.5″ Round Combination Infrared 85 Neutral Density 1.2 (ND) Filter
