Formatt Hitech Firecrest Pro 100x150mm Soft Edge Grad 0.9 (3 Stops) ND Filter

The Firecrest Pro, builds on the history and success of the Firecrest Brand. Our filters are manufactured using a rare earth metal coating, which is applied directly onto the glass using our advanced multi-coating technology. This is then bonded between further layers of the finest Schott Superwhite optical glass to provide industry leading scratch resistance and longevity.For complete light leakage protection, a component on blackout edging is applied to completely alleviate the risk of light leak that can occur through unprotected filter edges. The Firecrest Pro 2mm range is available in 100x150mm 2mm Graduated NDs. Firecrest Pro is rated for wider focal lengths up to 100mm. It is ideally suited to landscape photography. For photographers that need a longer focal length, please see Firecrest Ultra which is rated for extreme megapixel sensors and long focal lengths. ND Grads 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 grads are currently only available in soft edge grads, as they are the most versatile. Firecrest Multicoating 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. Firecrest ND Soft Edge Grad Another industry first with Firecrest is the development of IRND grads. All Firecrest ND filters, including grads, block infrared radiation, technically making them IRND grads. 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 IRND filters.
