The Hoya PROND is the most neutral balanced filter on the market. The PROND 100000 filters use ACCU-ND to yield a truly neutral color balance that will not add any noticeable color-cast to your images. 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.
