Photographer Fabio Galbiati impressed the judges with this image of a pristine mangrove

South African photographer Pier Mane took this image after deciding to 'turn away from the action'. He said: 'Weary of shooting sharks head-on, and keen to avoid bubbles in my shot, I decided to turn away from the peak action and the crowds it attracts. I wanted sun rays, dramatic foreground, background perspective, and - the cherry on top - to capture the 'master of the house' in all of its mystique. The three sponges were well-positioned to set the scene beneath the boat and it took countless shots to balance the elements I wanted, but perseverance, patience and practice all paid off'
