The Fantasea Line 67mm PinkEye Filter M67 is a color correction filter with a 67mm thread. It fits over an underwater housing's lens port and can be installed and removed during the course of the dive. The PinkEye Filter restores the pink color absorbed by green water and enables the production of vivid and colorful underwater images and videos. In shallow depths, this filter can serve as an attractive alternative to artificial light sources. It can be mounted on 67mm threaded lens ports, or on other lens ports by using an adapter.
