A strange wave breaking on the still waters of Loch Ness is thought to be the mysterious Loch Ness Monster by the amateur photographer who captured the image.
David, 50, was focusing in a swan at Fort Augustus on the south-west end when he spotted the “creature”.
David, of East Kilbride, said: “Out of the corner of my right eye I caught site of a black area of water about 15ft long which developed into a kind of bow wave.
“I’m convinced this was caused by a solid black object under the water. The water was very still at the time and there were no ripples coming off the wave and no other activity on the water.
“Water was definitely going over something sold and making the wave. It looks like the sort of wave perhaps created by a windsurfing board but there was nobody on the Loch at the time, no boats, nothing.
“It is something I just can’t explain.”
