EMPIRE STATE BUILDING AT SUNRISE - New York City, NY, USA
Although I did some photoshop work on this one (perspective/lens distortion correction, sharpening, slight contrast adjustment), the color here is pretty much straight out of the camera--I even desaturated it slightly because I thought the original was a little too bright.
This was taken from the roof of my friend's apartment building. I had to talk to about three different people to get the door unlocked and it was horribly cold up there, but I'm glad I went.
Unfortunately for me, the two best times of day for taking pictures outside are around sun-up (when I'd normally be sleeping) and sun-down (when I'd normally be eating).
