They show landscapes. Well, seascapes. But they are like landscapes. And all is natural. Isn't it? I think that makes these pics ideal candidates for the "Landscapes and Nature Gallery" (one below General Gallery), therefore I shall move them there right now.
But not before telling you that I particularly love the colours on the surface of the sea in the last of these photos. Nicely muted, but still best to be seen on the water!
