The Intova 46mm Red Underwater Color Correction Filter restores red color to your underwater photography. The color red only carries 15-20' (4.6 - 6.1 m) underwater. At depths below this, the color becomes washed out by the filtering effect of the ocean. This filter puts the red spectrum back into your underwater images. It is compatible with the IC-12 camera and any of Intova's cameras with a lower resolution.
