Hi! This photo is actually not from one of my projects---so weird! There a couple of those photos. Sorry I am no help on this one.

Hi. I am sorry, we don't know where the light is from. It is gorgeous! You could try contacting Artistic Tile to see if they know? But if you do have any questions about Tile and Stone we are here to answer any of your questions! Thanks! Thanks for your interest and sorry that we couldn't help! Have a great day!
