The 77mm Ring Mount LB Blue Intensifier Filter from Singh-Ray adds a subtle yet effective improvement in the color depth and warmth of an image. The effect added by the filter is just enough to enrich the color contrast in numerous outdoor scenes from landscapes to close-ups and even macro photos. As the filter adds only 1/3 of an f-stop more exposure, it is designed to be most beneficial for digital cameras.
