The FotodioX 6.6 x 8.5" Soft-Edge Graduated Neutral Density 0.9 Filter is a filter designed for use with the WonderPana 66 and FreeArc filter holder systems. It 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 dense and clear areas. Neutral density filters do not affect the coloration of the image and this filter provides up to a 3-stop reduction in light from entering a lens.
This filter is made of durable, optical resin (CR39) and measures 4mm thick. A carrying pouch is also included with the filter.
