Circular Firecrest ND Soft Edge Grad

from 78.13

The Firecrest Soft Edge ND Grad uses Firecrest technology to create the world’s most neutral grad filter, and is the perfect complement to the Firecrest ND filters. Soft edge grads are versatile filters used to balance the luminosity of a bright sky with the terrain below. The soft edge makes it easy to place the filter in the scene, especially over undefined horizons (such as mountains). Firecrest ND is a revolutionary new type of ND filter from Formatt-Hitech. Rather than dyed resin, Firecrest is a rare earth metal coating used to create hyper neutral NDs. These circular ND filters are made from Schott Superwite glass and feature rotating, stackable 7.5mm SuperSlim rings. Firecrest ND filters are hydrophobic, anti-reflective and extremely flare resistant, which increases contrast and visual acuity in challenging lighting conditions.

Soft Edge graduated filters transition gradually in density from the top of the filter toward the center, and although there is a horizon line, it is subtle. This allows for horizon transitions to be more easily hidden in a scene, especially with an undulating horizon line such as mountains, buildings or trees. Typically graduated filters are used to enhance the sky by balancing the luminosity of the sky to the luminosity of the terrain.

Firecrest ND 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. These glass filters are hyper-neutral across the visible light spectrum and also remove more IR contamination than any other filter - making them IRND filters. 

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, it is a rare earth metal coating process that is applied directly to the glass through an electrolytic process.

On rectangular filters, the Firecrest coating is sandwiched between the finest Schott Superwite optical glass, increasing scratch resistance and longevity. Firecrest reduces all spectrums of light (UV, visible, near infrared and infrared) almost perfectly evenly.

Another industry first with Firecrest is the development of IRND grads. Because Firecrest blocks both visible light and infrared radiation, all Firecrest NDs are considered IRNDs. Legacy graduated ND filters are manufactured from the traditional ND formulations originally developed for use with film and do not reduce infrared. Firecrest grads use the same Firecrest technology as their solid ND brothers. The result is a perfectly neutral graduated ND filter that pairs and stacks perfectly with even the highest densities of ND filter, and especially with other Firecrest & IRND filters. 


SuperSlim Ring

We manufacture our high quality aluminum rings to the most demanding tolerances, and these exceptionally slim rings minimize the chance of vignetting. SuperSlim rotating rings are 7.5mm thin and have threads for stacking. 


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.
