Here's what Ben says about his winning image: “I‘ve dedicated the last few years to shooting underwater, looking for new angles and a new way to shoot surfing and waves. Shooting surfing from underwater is a whole new world and I love it!
“Tahiti has some of the clearest water in the world so it was easy for me to take advantage of it and explore it as much as I could.
“This photo was shot during a freesurf session right before the WCT event in Teahupo‘o. This is Ace Buchan kicking out from the barrel through the wave, a technique to escape a close-out wave.
“Luckily I was right below, breathless with my waterhousing waiting for this moment and I was able to capture the whole sequence of it; this frame from the beginning of the sequence is the most powerful one because of the water around his face and body.”
