Blender type graduated ND filterThe HOYA ProND16 GRAD filter is a blender type graduated round filter designed to balance the luminosity of bright and dark areas within the image. Ideal for photographers specialising in landscape photography where skies can often end up burnt-out or foreground details lost in shadow. HOYA’s ProND GRAD filters help to preserve all the required rich pixel data, for photographers wanting to achieve the best results in the field, to the extent where post-production is often not necessary. HOYA’s ProND GRAD filters are round, screw-in type, feature professional grade optical glass and are completely neutral colour-balanced thanks to HOYA’s special ACCU-ND coating technology. The Blender style graduation offers a smooth, continuous transition across the whole filter making for a highly versatile filter for use in a variety of situations. The slim rotating aluminium alloy frame, allows for precise positioning of the graduated ND area with a special marker on the rim, showing the deepest density point.
Preserve Rich Pixel Data

Versatile Blender FilterBlender Graduated filters can be used for a variety of scenes, especially when the scenery and horizon are too complex to effectively hide the transition of a soft edge graduated filter. HOYA ProND GRAD filters are extremely versatile and easy to use, preserving rich pixel data in bright areas that makes editing your image easier and saves you time.
Rotating Aluminium Frame

Aluminium rotation FrameThe rotation frame allows for precise control of gradation, adjustable according to the composition or subjects positioned inside the image.

ND Deposition Process TechnologyHOYA ProND GRAD adopts ND deposition process technology that allows gradation to be distributed equally through the entire glass surface of the filter. To maintain true density value inside the image area HOYA adjusted the effective blending area in the way that the specified density would start and fade out inside that image area. That will help photographers to apply the required density to the image in the most effective way.
ACCU-ND Technology

Colour Shift Issue SolutionHOYA ProND Filter is a high technological product targeted for both still photography and HDSLR video markets. The ProND filters use HOYA’s exclusive clear optical glass that incorporates a metallic coating on front and back side to equally reduce almost all range of the light spectrum even in the IR area. The ACCU-ND technology used in the coating process perform a truly neutral colour balance that will not add any noticeable colour cast to your images.
