This image shows a fine example of the world’s largest fish at the whaleshark hotspot of Donsol in the Philippines. The conditions were grim for photography, so I was glad to get a decent image such as this one. The snorkeler gives an idea of the scale. Image taken on 20th March 2011 using a Nikon D200.Settings were ISO 640, f6.3, 1/60th second.
