Formatt Hitech Firecrest IRND 4x4 Neutral Density Filter 3 (10 Stops) - FC4x4ND3.0

 

Firecrest ND is a revolutionary new type of ND filter from Formatt-Hitech. Rather than dyed resin, Firecrest is a carbon metallic coating used to create hyper neutral NDs. The filters are made from 4mm thick Schott Superwite glass, and the multicoating is bonded in the middle to increase scratch resistance. Firecrest Filters are neutral across all spectrums, including UV, visible, and infrared. This 4x4” Firecrest ND filter reduces light by 10 stops.

 

The Formatt-Hitech 4 x 4" Firecrest ND 3.0 Filter is a solid neutral density filter providing a 10 stop reduction in exposure. This 3.0 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or longer shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily.

The design of this filter has been optimized for use with digital sensors and promote nearly flat attenuation of visible, UV, 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 provides a high level of neutrality across all three spectrums in order to eliminate color casts and ensure cleaner, truer blacks.

Sandwiched between layers of Schott Superwite glass is a 15-layer Firecrest multi-coating, which helps to minimize reflections and flare in order maintain truer colors and contrast. Since the coating is located within the middle of the filter, it is less prone to scratching or damage and results in a more durable and hydrophobic design. This filter measures 4 x 4" / 101.6 x 101.6mm and is 0.16" / 4mm-thick.

ND 3.0 filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.
Providing a 10 stop exposure reduction, this filter allows you to control depth of field and convey movement more easily.
Attenuates infrared light, as well as visible and UV wavelengths, to maintain color neutrality and suppress color casts due to increased exposure lengths.
The 15-layer Firecrest coating has been applied directly to the filter glass by way of a vacuum-formed, hard-coated, electrolytic process. The multi-coating is sandwiched between layers of glass for added water- and scratch-resistance.
Schott Superwite glass promotes maintained image clarity and its 4mm-thick design is well-suited to use in matte boxes.

About Firecrest ND Coating

FirecrestND is a quantum leap improvement over all previous generation ND and IRND products and represents the technological state of the art in scientific light modification. Firecrest is a radical departure in how ND filters are manufactured. Previous generation NDs were made by dying resin. Firecrest is not a dying process. Rather, Firecrest is a carbon metallic multicoating process that is applied directly to the glass through an electrolytic process.

Circular filters feature the Firecrest coating on the outside, making them anti-reflective and hydrophobic. On rectangular filters, the Firecrest coating is sandwiched between optical glass, increasing scratch resistance and longevity. Firecrest reduces all spectrums of light (UV, visible, near infrared and infrared) almost perfectly evenly. Firecrest filters are made from Schott Superwite glass.

Independent Test Data

These graphs show test results from an independent test performed at The Academy of Motion Picture Arts and Sciences (AMPAS). The test measured the spectral power distribution of tungsten light reflected off a spectralon target made of barium sulfate using a Photo Research SpectraScan Model 705 spectroradiometer. The results were graphed according to their wavelength (in nanometers) along the X axis, versus radiance (in watts per steradian per meter squared) along the Y axis.

In the top graph, the yellow line represents the baseline tungsten light reading reflected off the barium sulfate target. This graph illustrates the excellent filtration properties of both the ProStop IRND (shown in green) and the Firecrest ND (shown in blue). Both filters appear nearly flat from this perspective.

The second graph emphasizes the differences between the two filters by removing the baseline tungsten reading and zooming-in on the Y axis. On closer inspection, the graph shows the ProStop IRND strongly attenuating the near-infrared spectrum before returning to neutral attenuation of the infrared spectrum around the 730nm mark. Firecrest (shown in blue) performs perfectly linearly in the visible light spectrum, before completely eliminating the infrared energy at around the 700nm mark. Compared to the ProStop IRND (which is the previous benchmark in IRND filtrations) the performance shown by Firecrest ND is nothing short of revolutionary. Firecrest ND truly is the future of ND filtration for digital sensors. Results in-the-field confirm the test data. The new Firecrest ND is amazingly neutral regardless of the camera make or model used.
