The Formatt Hitech 67x85mm ProStop IRND Solid Neutral Density 2.4-3.0 Filter Kit is designed for use with the Formatt Hitech 67mm Aluminum Modular Filter Holder and includes three solid neutral density filters. These filters have filter factors of 256x, 512x, or 1024x that provide 8, 9, and 10-stop reductions in exposure, respectively. Their 2.4, 2.7, or 3.0 densities each create a darkening of the entire image, allowing you to photograph with a wider aperture or longer shutter speed than normally required in order to better control depth of field or convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.
The designs for these filters have been optimized for use with digital sensors and promote nearly flat attenuation of visible 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 the visible and infrared spectrums in order to eliminate color casts and ensure cleaner, truer blacks.
Each filter in this kit is constructed from optical resin for clarity as well as color fidelity and measures 1.5mm thick. A carrying pouch is also included with this filter kit.
