The underwater world is fascinating; mind mindbogglingly beautiful in places, particularly in the Coral Triangle between Indonesia, New Guinea and the Philippines. Seeing whales in close-up is mind blowing; you rarely see all the animal from above the water but to see the whole animal underwater is fantastic, particularly when you eyeball a Whale Shark or Humpback Whale.
All my underwater images were taken from the water surface while snorkeling. These days I wear a snorkeling vest for safety, as I am not as fit as I used to be.
Most of the underwater images were taken with my Fuji W3 camera in a Recsea housing, but in Papua New Guinea I also used a pair of GoPro 3 Black cameras linked together in a GoPro underwater housing.
