Fireworks on the waterfront in Tampa, Fl. Taken from Tampa General Hospital.
This shot was taken on a Nikon D200 with a "Strike Finder" lightning trigger. I worked my other camera while the trigger setup captured over 150 images without my assistance. Just set it up and sit back and watch!!! I did some minor tweeking in Lightroom 4.
