Before I learned all the what nots on my digital camera I took some interesting Fireworks pictures one Fourth of July. I decided to call them my Fireworks Art.
Beautiful shots! When I got back into the Chemistry of Powders and Explosives, studying firearms ballistics, I found that contriving such beautiful bursts of burning bits of chemicals requires painstaking care in preparation. Quite a lot of time and effort is spent to get back a 2 or 3 second burst of Pyrotechny. As a kid, the municipal displays featured aerial bombshells which produced only huge, white flashes and enormous explosions. Sitting a quarter-mile away, we could feel the concussion against our bodies! My favorite was the one which fired 5 or 6 smaller explosions followed by one gigantic blast, the flash I guess was big as a house! Today's commercial displays no longer seem to contain those biggies. Frank
I had a book about U.S. Naval Vessels in which a pic showed the projectile caught in flight, shortly after firing, of a 16" gun on a battleship. The image was crisp. Such projectiles could travel 20 miles, devastating the adversary. Sadly, the book is gone today. Who would've thunk anyone would care to see, years later....Frank
