The HOYA PROND filter kit is an indispensable filter kit. The kit consists of 3 ND filters - PROND8, PROND64 and PROND1000, allowing the photographer to capture the world in different expressions. PROND8, PROND64 and PROND1000 are the main ND filters that can be used to realize three common and frequently used expressions among photographers. The ACCU-ND technology used in the coating process results in a truly neutral color balance that will not give your images a noticeable color cast. HOYA PROND filters incorporate a precisely engineered thick aluminum frame to prevent light leakage to achieve correct exposure and color balance. PROND8 (3-STAGE) HOYA PROND8 is essential for shooting with fast lenses at wide open aperture during the day, which is perfect for portraits with shallow depth of field. The subject appears sharp and clear on the soft, blurred background. PROND1000 (10-STOPPS) HOYA PROND1000 is indispensable for expressing an unreal fantasy world thanks to the reduction of the amount of light by 10 stops. Widely used in seascapes to blur the waves, on the street to apply the movement of clouds, and in architecture to erase moving people. PROND FILTERS IN VIDEO PRODUCTION ND filters are also an irreplaceable tool when shooting video. For example, if you are shooting with a Sony camera in slog mode, the ISO value cannot be set below 800. To obtain a natural motion blur, it is recommended to adjust the shutter speed to the image/rate setting. The combination of PROND8+PROND1000 gives the same effect as ND8000, which makes it possible to capture the sun's surface with solid color and visibility of the black spots without overexposure.
