Imagine snorkelling in the warm blue waters surrounding The Maldives. Your viewpoint may resemble this remarkable photograph by Stefan Hafele Photography, which reveals the view both above and below the waves. Under the waterline, tropical fish swim around the coral reef, their bright colours gleaming like jewels in in the dappled sunlight. Above the waves, palm trees and lush green undergrowth edge the warm white sands, and the whole scene is topped with a deep blue sky.
