Underwater photography came into being only a few decades ago. Its growth was hindered by the limitation of the available photographic equipment. However, with the development of science and technology, underwater photography has become a popular pastime. Most diving enthusiasts bring a camera with them when they go diving to take pictures of the colourful underwater world. Although underwater photography is no longer an elitist pursuit, but there are still very few professional underwater photographers; and there are even fewer Chinese in this industry. The five episodes of “Sea World Odyssey – Through My Lens” document the work of five Chinese underwater photographers from Asia. We followed them to Indonesia, Palau, Fiji, Brunei, and China, diving with them into the colourful underwater world to share their exciting experience in encountering amazing marine life and ancient cities that have been submerged under water.
