Bunaken Island in North Sulawesi, Indonesia is famous for its superb diving conditions. Visibility under water of more than 20 meters are quite normal. However when I reached the island the viability underwater was very bad due to heavy storms. So I decided to make the best out of it and captured the storm approaching during sunset.
