Knowing the beach, and knowing also that the foreground wouldn’t have been interesting I would have done similar, it’s all about the sky in this case. I might have had a wee bit more beach on the bottom, but not 2/3 worth…but that’s me!
Thanks for the comments! I didn’t have a tripod with me at the time so I had to let the foreground silhouette, which is partly why I included so little of it. It was all about the sky though,as you say!
