Hi:
I am new to the forum, so please bear with me :-).
I have been shooting fireworks for decades, most recently with a Canon 5D, and most of my results are quite good. I do the usual things that are always recommended (tripod, remote, "B" setting, longish exposure, aperture f/11 to f/22, low ISO etc). The one situation I am still having problems with is the Grand Finale: even when I keep the shutter open for a shorter time, the colors seem to be washed out, and the superimposition of the fireworks makes them lose detail.
I should add that in many cases I have no choice but to be "too close", i.e. the setting is such that if I try to move farther away, I end up behind houses or trees. I have had less trouble with the Grand Finale when shooting from across a body of water (lake, river, sea) - see attached images.
Any suggestions would be appreciated.
Thanks,
Roberta
