It's too hot a summer here, and it makes me urging for swimming. This was shot along the eastern rim of Taiwan. Geographically the island was erupted straight from the seabed many years ago on earth plate/volcanic movements. It created the tall, straight, dramatic and dangerous coasts. The color indicates a deep and breathtaking seabed, yet clear and unpolluted water. I find the sea color amazing and I frequently return to this picture.
