This was my first real effort on fireworks. Even though I did some scouting, I couldn't find much of a foreground to work with so I pretty much stuck with the stuff in the sky.
7D, 50 1.2L, 6s, ISO 100, f11 or f16, manual everything, tripod and release---these are cropped up to 50% because I was fairly far from the action (less people and lights). This was also the first time I gave the 50 1.2 a serious workout----I am very pleased with this lens---so far.
