I think that most people don't realize how truly amazing the undersea world is, so I take pictures to show them what it's all about.

Richard "Harry" Harris is an Australian Anaesthetist and Physician in Diving Medicine currently living in Vanuatu. He started diving in 1979 and took up underwater photography soon after with a Nikonos III, developing his black and white images in a home darkroom. Very much still an amateur photographer, his day job is just an excuse to pay for his diving addiction which seems to be getting worse with time not better. Now a keen tech diver, he is taking his camera further into caves and deeper to wrecks on CCR, still searching for the perfect shot! In 2006 Harry and his long suffering family will return to Australia where his focus will be on diving the remote and beautiful caves of Oz. More of his work can be seen at

Jill’s love of the underwater world began in her Canadian homeland, but her exploration of caves has taken her all over the world. Jill has received many accolades for her work including being inducted into the Women Divers Hall of Fame, being named Canadian Technical Diver of the Year and a Fellow of the National Speleological Society. She has received international recognition for her work as a filmmaker and has been honored with a CINE Golden Eagle, a Gold Aurora, Best Exploration Film from the Explorer’s Club Film Festival as well as many other awards.

Born and raised in the Pacific Northwest, John Rawlings spent much of his childhood alongside his avid fisherman father gazing down into the emerald green waters of Puget Sound and wondering what really lay beneath the surface. Finally learning to dive in the mid-1970s, it wasn't long before he developed a burning desire to photograph the many colorful animals and scenes he regularly saw while diving so that he could share his wonder with "topside friends".

Starting with a used Nikonos II and a dented flash-bulb system, John became a self-taught photographer as he struggled to find the best methods to photograph the underwater creatures and sights of Puget Sound, the Strait of Juan de Fuca, and British Columbia. Often having to deal with typically Northwest low light and poor visibility, these conditions contributed much to the manner in which John views both his subjects and the methods that he uses to capture his images. In the early days he would emerge from each dive with an old breadbag full of used bulbs lashed to his weight belt and a "wee bit" more knowledge about Pacific Northwest underwater photography bouncing around in his head. While his equipment has become more modern, John's quest for increased knowledge and skill remains never-ending.

Having traveled to a variety of locations throughout the world, John still treasures the underwater world of his home waters above all others. Year-round.....sun, snow, wind or rain..... he can be found striding out of the surf on a desolate beach or climbing back into a dive boat, his camera again containing new images from the cold, green waters of the Pacific Northwest.
