This 2-stop, 6.6 x 8.5" Hard-Edge Graduated ND Filter from FotodioX is designed for use with the WonderPana 66 and FreeArc filter holder systems. The 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 hard-edged line of transition between the dense and clear areas. Neutral density filters do not affect the coloration of the image and this filter provides up to a 2-stop reduction in light from entering a lens. This filter is made of durable, CR39 optical resin and measures 4mm thick. A carrying pouch is also included with the filter.
