I only use natural layers like this one. I will explain to you what you see. You see with my lens through an old window of an abandoned house in my city. I am standing on the backside of the house and you can see a window on the front side, with white paint on it, and with sunshine on it too. On the left you see also the reflection of a few windows behind me of an other building reflected in the same -old glass window- you see the painted window through. Well hope you understand now. :-)
