Fotodiox Pro 6.6x8.5" Graduated Neutral Density .6 (Grad-ND4, 2-Stop) Hard Edge Filter (works with WonderPana 66 Systems)
Fotodiox Pro 6.6"x8.5" filters are the strongest in the industry at 2mm thick. Fotodiox 6.6x8.5" filters are practically unbreakable and are guaranteed spectrally neutral to within + or – 3 in the a and b channels of the lab color space. Reverse grad filters are primarily used for light reduction in skylines of landscape shots. The reverse grad is a vital tool if you are looking to take sunrise or sunset shots. This is because the ND part of the grad is upside down, with the darkest area is near the center, graduating to approximately one f-stop lighter on the top part of the filter and the lower part of the filter is clear to allow balanced exposure with the foreground. This ensures the maximum light reduction when the sun is at or near the horizon. This filter is made by Fotodiox Pro specifically for the WonderPana 66 & FreeArc Systems.
