I shot this Manta Ray feeding on plankton on a night dive off Kona on the Big Island of Hawaii. It was shot with an Olympus 350 with Olympus housing and a fisheye lens and two Sea and Sea 110 alpha strobes. Camera settings were f5.6 1/125 sec ISO 100 fisheye lens at 8 mm. The photo was shot in approximately 25 feet of water.
