The physics of light. If you look closely you will notice that the "figures" are directly in between the camera and the windows on the house. More
on the windows in a bit, but first notice that the sun is either setting or rising so it is very low on the horizon.
Next, look at the shadows on the ground. They form a line that is about 45 degrees off to the left of the plane of the front of the house. What I mean
is basically that standing in front of (behind?) that house with your back against the wall you would see the sun to your right (reverse POV) about 45
degrees from where your nose is pointing. That angle is important.
Now imagine yourself standing in the same spot. Where would the plane (ie. camera) be then? About 45ish degrees to the left of your nose. Now we are
The law of reflection states that the angle of incidence equals the angle of reflection. So if there was a reflective (known as specular) surface at
an angle roughly corresponding to the plane of the front (back?) of the house then we would expect there to be a lot of reflected sunlight in the
general direction of the camera.
The shiny surfaces in this instance are the windows of this house. The reason the light bouncing off the windows doesn't cause a lens flare is
because the camera is at about the same height as the sun (in degrees from the point of view of someone on the ground) and both are looking down at
the house. It is required that there be a second reflector in this case for the sun to be captured by the camera.
What you are seeing is that very secondary reflection. The light from the sun is reflecting off the windows of the house and then reflecting off the
"bituminous concrete" because it is either wet or dewy or just reflective enough.
If you don't think dry "black-top" is reflective enough for this effect just go for a drive just after sunrise. While you are driving into the sun,
the light bouncing off the asphalt is more blinding than the sun itself is!
