The 55mm URPRO CY Filter for Tropical Blue Water from Snake River Prototyping is a color correction filter for underwater housings with 55mm threading. Because water alters the color of light, tending to absorb more red as you go deeper, filters are essential for retaining natural color balance. The Cyan Filter is best for use in tropical blue waters at depths between 12 and 60 feet (4 to 20m).
The Cyan Filter features an ultra low-profile filter ring designed to avoid vignetting when used for cameras with very wide lenses, such as the GoPro HERO3. Because of the low-profile design, there is no outside threading to allow you to stack additional filters on top.
The Cyan Filter is recommended for the following dive sites: French Polynesia, Belize, Cozumel, Caribbean, Maldives, and the Great Barrier Reef.
