A composite photo (made up of 17 individual 12-megapixel photos) of the left wing of the Cannon House Office Building in Washington, DC. Its total resolution is approximately 64 megapixels. All sorts of interesting little details can be seen at full res.
For example, there’s a “Do Not Remove” sticker on one of the windows, probably left there from the time when the windows were replaced, way back when. And in spite of the fact that there’s electrified wire strung over all edges of the building, to discourage birds from building nests, one enterprising sparrow found a spot where it could build one.
I posted this photo at a width of 1000 pixels, to show more detail. Click through to view it at that size. You can find the full res original in my Washington DC gallery, inside my photo catalog.
