The sky and the sea; two of my favourite elements in this one image by Italian photographer Graziano Panfili, titled How deep is the sea? What draws me in is the mirroring of colours—the intense hue of green-blue— between sky and sea, creating a strange sense of inversion, where sky and sea are almost interchangeable. The photograph was taken in San Felice Circeo, a small village by the sea in Lazio, Italy. Actually, there are four elements I love in this photograph: the sea, sky, clouds and a horizon; horizon lines fascinate me!
