The 85 x 85 Formatt-Hitech Firecrest ND Filter Kit contains 4 Firecrest ND filters, ranging in density from 2.1 to 3.0 to provide a reduction in exposure from 7 to 10 stops. By darkening the entire image, you can photograph with a wider aperture or slower shutter speed than normally required for greater control over focus, movement, and brightness.

The design of these filters 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. These filters provide 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 filters. Each filter in this kit measures 3.3 x 3.3" / 85 x 85mm and is 2mm-thick, making it compatible with the Formatt-Hitech 85mm Filter Holder.

Q: 6. Is there a front and back to this FirecrestUltra filter? Which side to install the gasket on? I intend to use it with LEE filter holder. The filter's two sides have a different color sheen when you looking at it under an angle.. side with writing has a hint of reddish/ black color reflection, and side without writing has black / bluish reflection. What is recommended filter orientation while using in the filter holder.. does it make any difference if either side is facing away from the lens? Format-Hitech FirecrestUltra100x1003.0

A: FYI! This is the Information from Format-Hitech.USA The colors you see are due to light passing through the filter. These are not directional but it is always good to put the engraved writing on the filter facing away from the camera for identification when in the holder as well as on the chance that another type of filter is directional.
