The Fotodiox Pro 6.6 x 8.5" Reverse Graduated 0.6 Neutral Density Filter is designed for use with the WonderPana 66 & FreeArc filter systems. This 2-stop neutral density filter is clear in the lower half but graduates from dark to light towards the top. This holds your foreground while "toning down" the horizon line and upper half of the image. For the nature or landscape shooter, this is an ideal filter that can save what might ordinarily be an impossible shot to capture on film or digital, especially with extremely high contrast sunset and sunrise scenes.
The graduation also has a soft-edge for a more natural look and the filter is constructed from 4mm thick optical polycarbonate (CR39). Also, the filter includes a carrying pouch for protection when not in use.
