Video from the Northern Lights Pyro Club
2009 Spring Demo.
Grid = 60 Feet High and 80 Feet Wide per block
I took the opportunity with this shoot to try out a number of different camera settings, many (most) of these videos are to dark The grid and timer overlays are useful, but if you want to get a true feel for how the product looks there are better videos out there.
Some of these products can be found in the series from my Mess's Fireworks 2008 Spring Demo Gallery
with better video quality and view of the effects but tighter in and without grid overlay or much of a sense of perspective.
