Hello,
I apologize if the is off topic.
When I watch a fireworks display on TV, I notice many productions
include multiple angle shots superimposed to make it appear as there
are more fireworks than actually are actually occurring at the time.
Sometimes the second camera is delayed a little so as to mask the
symmetry. Surprisingly, most other viewers are incredulous when I
point this out, even when I show that the symmetry proves it can't
possibly be a single shot.
Can anyone provide information verifying they do this, and how it's
done?
I've seen some where the camera(s) is/are panning, which makes this
process complicated unless the cameras are synchronized. Sometimes
there is a single background. If it's a multi-shot, then how is the
background 'subtracted' from the picture?
Thanks so much. Not that I'm losing sleep over this (well, maybe a
little), but this has bugged me for the 10 plus years I've noticed the
practice.
