Daybreak on Washington
Sunrise, Washington, DC.
"Sunrise", "sun up", and "daybreak" all refer to the moment at which the tip of the sun peaks over the horizon. (Wikipedia, Sunrise (as of October 2, 2012))
On September 30, when I took this photo, sunrise was technically at 7:03. I took this photo at 7:08, but because the height of the buildings mask the horizon, the tip of the sun didn't appear until moments after I took this photo.
