In underwater world, you could see variously colored fishes and corals which cannot be seen onshore. I wondered how it would be like to see those colorful creatures through soratama lens. This was the start of my underwater soratama photography.
By using extension tubes and close-up lens, I managed to make the camera size compact, then put it in the waterproof camera cover. Underwater soratama photography was very interesting as I had imagined and see potential in this. With the same lens tube setting, you could take small objects with a few centimeters up to a large group of fish, corals and soft corals which measures few decimeters. Not only the object in the center sphere but I also enjoy the background image which is taken through the filter.
