Underwater photographer of the year – winner. Dancing Octopus by Gabriel Barathieu (France). Location: Island of Mayotte, off the coast of south-east Africa. “Balletic and malevolent”, one judge said of this octopus, hunting in a lagoon.

These kaleidoscopic images are the work of one persistent photographer’s efforts to capture vibrant hues at the exact moment a wave breaks. Ryan Pernofski‘s stunning shots feature brilliant yellows, reds, blues and purples as an array of sunlight hits the water at the perfect time. What’s even more impressive: Ryan, a 27-year-old Australian, began shooting his popular masterpieces without using a professional camera, taking his iPhone out into the water instead. Ryan began experimenting with this method in 2012, using an underwater housing to protect his phone, as he could not afford a professional camera. (Photo by Ryan Pernoski/Caters News Agency)
