Equinox offers Bluewater and Greenwater color correction filters. The Equinox Color Correction Filters bring to life the complete color spectrum under water. The Equinox Color Correction Filters need only natural sunlight to restore the 'Beauty from Beneath'. Both filters are ideal for all video, still and digital cameras from depths between 10 and 70+ feet. These filters push on the end of your housing over the domeport shroud and are only compatible with the Pro6/HD6 and Pro8/HD8 Series of underwater video housings.
