Hoya RA64 Blue Enhancer Filter Ø 82mm

The Hoya Blue Enhancer filter amplifies and enhances blue colours without negatively affecting other shades. This is excellent for brightening seascapes and partly or completely overcast skies, but is also suitable for situations where polarisation filters, due to the direction of the sun, are not effective in increasing the saturation of a blue sky. For increased contrast, Hoya recommends using the Blue Enhancer in combination with a circular polarising filter.
