Tungstene, high-technology image interpretation software which combs through the information contained in digital images to detect potential tampering.
I’ve looked it up. Frank Davis’s home (In 1958) was at 2994 Kalihi street, Honolulu Hawaii.
Look at it with Google street view. (If you are not sure which house is which, look at the garbage cans. They are clearly labeled with the house address.) The room in the front (rightward side) of the house appears to be the most likely location. Had I lived there, I would have put the Christmas tree in that room so that it could be seen from the street through that large front window.
Notice also that the side window replicates that peculiar spacing (of the glass supports) shown in the picture of Ann Dunham. (You have to enlarge it to see it. It *IS* distinguishable, but not terribly clear.)
To give you peace of mind as to the veracity of that address, look through this link and you will see it.
