Equinox 43mm Underwater Color Filter for Blue Water

The Equinox 43mm Underwater Color Filter for Blue Water is a red color correction filter designed specifically for underwater photography use. This filter counters the overwhelming blue color cast that is caused by saltwater, which can lessen the vibrancy of underwater subjects. A red filter mimics the use of artificial lighting and helps to balance colors to their natural appearance. This filter is ideal for use in waters 10-70' / 3.1-21.3m deep.
