Formatt Hitech 165 x 200mm Firecrest Graduated ND 0.3 Filter (Vertical Orientation)

The Formatt-Hitech 165 x 200mm Firecrest Graduated ND 0.3 Filter helps to darken specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the other regions of the image. The filter is densest at the edge and tapers to clear by the middle, with a soft-edged line of transition between the density and clear areas. Neutral density filters do not affect the coloration of the image and the 0.3 density provides a 1 stop reduction in light from entering the lens.

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.

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 maintain truer colors and contrast. The multi-coating is also scratch-resistant and hydrophobic to benefit the overall durability of the filter. This filter measures 6.5 x 7.9" / 165 x 200mm and is 0.08" / 2mm-thick, making it compatible with the Lucroit 165mm Filter Holder. Its vertical orientation indicates that the density's line of transition runs parallel to the short side of the filter.
