Formatt Hitech 100 x 150mm Firecrest Ultra Reverse Graduated ND 0.6 Filter

EAN: 886235212919

Exhibiting improved clarity, flatness, and reduced reflectivity, the 100 x 150mm Firecrest Ultra Reverse Graduated ND 0.6 Filter from Formatt-Hitech is ideal for photographing sunrises and sunsets due to its unique design where the density of the filter is greatest in the middle and tapers off to the edge. By reversing this direction of the graduated ND, you are able to more accurately control bright horizon lines while retaining exposure in the foreground and sky.

Designed using inspiration from their cine Firecrest filters, these Ultra filters receive an additional lapping and polishing process during production to ensure lower reflectivity and improved clarity and sharpness. This filter has also been optimized for use with digital sensors and promotes 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.

Applied to the outside of the Schott Superwite glass construction is a 15-layer Firecrest multi-coating, which helps to minimize reflections and flare in order to maintain truer colors and contrast. The multi-coating is also scratch-resistant and hydrophobic to benefit the overall durability of the filter. It measures 3.9 x 5.9 / 100 x 150mm and is 0.08 / 2mm-thick, making it compatible with the Formatt-Hitech 100mm Filter Holder.

The Ultra Firecrest series of filters exhibit greater clarity and have lower reflectivity than the original Firecrest filters. Borrowing from the range of Firecrest cine filters, the Ultra series filters undergo a secondary lapping and polishing process after the initial polishing and bonding stage. This additional step helps to ensure flatness and consistency for improved image quality.

Reverse graduated filters place the most density in the middle of the filter to accommodate bright horizons and other situations where the brightest part of the image lies in the middle of the composition.

The 0.6 density provides a 2-stop reduction in light in selective areas.

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 outside of the filter glass by way of a vacuum-formed, hard-coated, electrolytic process. The multi-coating is water- and scratch-resistance for greater overall durability.

Schott Superwite glass promotes maintained image clarity and its 2mm-thick design is compatible with the Formatt-Hitech 100mm Filter Holder.
