This one started out as a snap, shot from the hip as I walked past these two kids on the beach. As you can see from the original, my composition wasn't great:

After rotating the image, producing two versions from the same file (one optimised for the sky, one for the foreground), and with the addition of a few Curves and a slight shift in colour balance, it looks much better.

As for the shot itself: when I was a kid I suspect that I'd have run into the sea and joined them but, as an adult, I can't think of anything less enjoyable than sitting half-clothed in the Irish Sea on an overcast day :-)
