Hoya Graduated ND 77mm

overview

The Hoya 77mm Graduated ND10 Filter is a graduated neutral density filter that helps to specifically darken skies and other bright 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 design of this filter incorporates a rotating mount to allow precise positioning of the density over a selected area of the scene for greater control in darkening the brightest areas of an image. A neutral density filter does not affect the overall coloration of an image and helps to reduce the amount of light entering the camera lens in order to enable the use of wider aperture settings or longer shutter speeds. 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 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.
