July 4th Fireworks - Happy Birthday America!

These shots of the Oklahoma City Bricktown fireworks program were taken from the State Fair Park about 6 miles away.  The camera, a Canon 20D, was setup on a tripod with a 135-400mm Sigma telephoto lens.  The camera was set to ISO 800 and f/32 and repeated exposures were made throughout the program using a TC80N3 cable release set for 8 second exposures.  In post processing, seven exposures each were stacked and cropped to create these images in more or less a timeline of the entire program. 

Each page shows both the full frame and the cropped shot.
