Yes, I know that maybe I'm a little boring coming back to the City of Arts and Sciences, but it's one of my topics in my photo stream. This blue glow, at the entry of the elevator, it's natural since it's created by the light that enters in the cavity of the elevator from outdoors, obviously the image was shot at the blue hour hence the blue tones.
Thanks for stopping by and my apologies if I haven't yet replied your comments.
