Anyone that knows me knows I love it when something blows up.  Now my relative position to the object also enhances the experience.  I'd say around 200 yards and I am all good....and let er' rip.   Found this video of the Fireworks Display n London for the 2012 New Years and I am amazed.  I have never seen anything like it.   I had no idea it was even possible to shoot fireworks out of the clock tower...and ring Big Ben as many time as you wanted!  Super sweet!  Also the amount of camera positions makes the entire show even better.  Happy New Year and Enjoy it in HD!
