we had a family holiday in the Maldives recently, and I managed to get some nice dives in. Here's a short clip:
The hammerhead was at 30m and it was 6 a.m., so more like a night dive. The blue plankton looked cool. Filmed on Pana GH2 (hacked), with bit of white translucent plastic detergent bottle as an "expodisc" white balance filter.
