The giant mantas are one of the reasons for visiting Mexico’s Socorro Islands. This image, taken from above, shows a manta cruising past a diver over the rubble strewn ridge at El Canyon at San Benedicto Island. The size of the manta compared to the diver gives the image that extra “context” where you can’t fail to be in awe of the animal’s size. Image taken on 28th May 2009 with a Nikon D200/Subal housing and a 10.5mm fisheye lens. Settings were ISO 100, f8, 1/100th second.
