Oh! I forgot, I was using a Bogan Tripod with a Manfroto 3130 quick release head. Sucker weighs a ton too... I didn't really play too much but this is my 5th year shooting this fireworks show and its within walking distance from my house so its convenient. The first time I shot fireworks I let the camera do the work. Maybe 3 shots out of 100 turned out. All the others have been manual settings or on Shutter priority. That way I can play with exposure times and not have to check Apertures each time. Its a system that works for me.
