The GRADUATED ND 10 balances exposure between the lightest and darkest areas of a scene allowing better tone and detail to be recorded in these areas of the image.

The Hoya GRADUATED ND 10 is darker at the top giving that area a 3-stop light reduction and then fading evenly to a 1 stop light reduction at the bottom. This creates more balanced exposure between the lighter and darker areas of a scene, especially useful for photos that include the sky. The aluminum filter frame rotates so the darkest area can be positioned as needed.

The Hoya GRADUATED ND 10 filter uses a Hoya super clear optical glass in a wedge layer that is matched and perfectly bonded to a ND filter glass wedge layer to create the gradual ND effect.

Neutral density filters are designed to reduce the amount of light entering your camera lens and do not have any other effect on the image. Reducing the amount of light allows for the use of wider apertures or slower shutter speeds for creative and dramatic affect in bright lighting conditions.

The ACCU-ND technology in the Hoya PROND filters yields a truly neutral color balance that will not add any noticeable color-cast to your images. The Hoya PROND series is aimed at the still photography and HDSLR video markets. The series provides 9 filters from two stop to 10 stop light reduction.

The Metallic ACCU-ND coating on the PROND filters do not color shift as you move from one density to the next, a common problem with other series of neutral density filters. Now you can set your white balance once and have the same color balance even if you need to change filters due to changes in lighting, or for creative effect.

The PROND filters use Hoya's exclusive clear optical glass that has a metallic ACCU-ND coating front and back to create the neutral density affect.
