A blender type filter is highly versatile and can be used in a variety of situations, especially when the scenery and horizon have a complex or uneven structure. HOYA PROND16 GRAD filter incorporates ACCU-ND technology, providing the highest quality and the best experience for the photographer. For JPEG users it is a crucial output. Graduated filter helps to adjust the luminosity of a bright sky with the terrain and as a result we have excellent, overall well exposed ready-to-go image. For professional photographers who work with RAW data, graduated filter will help to preserve rich pixel data in bright areas. That will make further post-editing process easy and time-saving. Especially this issue concerns bright areas, where pixel rescue is the most difficult process. Blenders can be used for a variety of scenes especially when the scenery and horizon are too complex to hide the transition of a soft edge filter. Blender type HOYA PROND GRAD filters are extremely versatile and easy to use. HOYA PROND GRAD adopts ND deposition process technology that allows gradation to be distributed equally through the entire filter glass surface. However, to maintain true density value inside the image area we 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. HOYA 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 color balance that will not add any noticeable color cast to your images.
