Thames Festival Finale Fireworks
Image by Dominic’s pics
Component of a Set / Virtual Firework Display Slideshow documenting the firework show that marked the end of the "the mayor’s" Thames Festival in London on the evening of Sunday September 11th 2011.
The show was presented by Pains Fireworks.
A delay in the begin of the display from the scheduled time was attributed by the crowds to incompetence by "Bumbling Boris" Johnson – the London Mayor – element of the British patrician "limited liability" ruling class. "I’m in charge, but if something goes incorrect, somebody else will be sacked…"
Like the intense audio dynamic variety of Taiko or Samba drumming, it is not really feasible to record the visual brilliance of fireworks with a camera. You have to encounter firework displays reside, in particular person. These images were taken at the slowest sensor speed (ISO one hundred), maximum aperture (to minimise diffraction "glare" effects) and with a range of exposure times ranging from about .5 to 2 seconds. The intense light caused some "bleaching" of the paths of the lights, and so the colours have been enriched if Photoshop. (In retrospect I may have utilized a slightly smaller sized aperture.)Additionally, the river and land regions have been selectively lightened in Photoshop. Fortuitously, a gentle breeze brought on the smoke to drift eastwards, away from my vantage point on Waterloo Bridge, so the view of the fireworks was relatively unobstructed by smoke.
Fireworks date from at least the 7th century in China. The colours are believed to have been traditional incandescent "black physique" bonfire colours: red, orange, yellow and white. (It is theoretically attainable to produce pale blue just by heating, but this needs impracticably high temperatures. It is not achievable to heat something to "green hot" or "purple hot".) It is believed that from about 1830 in Italy metal salts had been introduced to create a wider, richer hued, spectrum of colours by chemical luminescence. This strategy can be problematic, as it can be difficult to generate steady, sensible, chemical compositions. It has been suggested that some shades of green are nevertheless hard to obtain.
