Formatt Hitech 67 x 85mm ProStop 1.5 IRND Filter

The Hitech 67 x 85mm ProStop 1.5 IRND Filter is a solid neutral density filter providing a 5 stop reduction in exposure. This 1.5 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or longer shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily.
