Here is one I shot this Saturday. It was so windy out I only got 2 shots in before packing up and leaving. It was so uncomfortable being out on the beach, we kept getting sand blasted and everyting kept getting tipped over, however the photos turned out ok. I always say crazy weather makes good pictures. Here is a full tutorial on how I shoot this kind of photos.
