Spectrum of Sunrise

I couldn't resist this view this morning.  I was sitting reading before sunrise with this sky and horizon in front of me; I could ignore it no longer.  The small objects are fishing vessels on the calm sea.

The structure on the land (an island) is the landing jetty for the ferry from Fuseta, a fishing village around me.  The sea sometimes changes the shape of the island, of course, but that island is also some level of protection for the village and for the nature reserve of Ria Formosa.
