Downtown Pittsburgh/fireworks

Downtown Pittsburgh/fireworks (crop), originally uploaded by btezra.

A crop from a larger frame of the area in Downtown Pittsburgh closest to the fireworks at PNC Park on the North Shore.
It was 1/2 way through the fireworks show, the smoke cloud was fairly large and covered most of the bldgs. in downtown, but I just liked the firework here, finding it hard to control the exposure of the firework with 10-30 second exposures.
