The Hoya 49mm PRO ND4 Filter has several uses and offers the possibility to achieve otherwise unachievable results. ND filters appear grey and reduce the amount of light reaching the film. They have no effect on colour balance. The ACCU-ND technology in the HOYA 49mm PRO ND4 FILTER Neutral Density yields a truly neutral colour balance that will not add any noticeable colour-cast to your images. The Hoya PROND series is aimed at the still photography and HDSLR video markets. The Metallic ACCU-ND coating on the PROND filters does not colour shift as you move from one density to the next, a common problem with other series of neutral density filters.

Now you can set your white balance once and have the same colour balance even if you need to change filters due to changes in lighting, or for creative effect.
