I had a 5-day trip to Washington DC for a conference in January of 2009, right before the historic inauguration of 44th President Barack Obama. Although I was very busy with meetings and stuff, but I still had chance to explore some parts of Washington DC, the capital city of the United States.
Of course I always travel with my camera and lenses. But this time, I was not able to drag all my photographic stuffs, just my camera, two lenses and my ND filter, not even my tripod.
These are some shots taken in Washington DC (mostly around the National Mall and downtown area).
