Serendipitous sand

Some take pride in presenting photographs that are "straight out of the camera". Well, this one is straight out of the camera! The trouble is that I have a new camera and it does things that I have yet to discover. I must have inadvertently set one of these undiscovered features with this result. I quite like the effect and must try to find out how I achieved it! If you are wondering, these are ripples on the beach left by the receding tide.
