Depth of focus

Ace Wus, from Taiwan, goes where few photographers dare travel to capture alien-like images of the sea creatures that live deep below the ocean’s surface. He uses blue light to create images of a hairy frogfish, far left, transparent octopus and ghost pipefish that glow with an incredible vibrancy. Ace, 42, who was highly commended in the Underwater Photographer of the Year 2018 awards, said: “It’s difficult to describe the beauty of the ocean with words, so I choose pictures.”
