Thanks for the comments. That morning was wonderful, as following some rain the night before, there were clouds in the sky. Add to that the side low angle side lighting coming from the North, plus low tide, and some tide pools, we get some nice elements.
The problem is to get up at 5 am:) As for people walking the dogs, they make for interesting subjects, but during the summer season, they are not allowed to be there... dog poo and such...
