When a Santa Ana wind came blowing in off the Mojave, carrying with it dirt, grit, disease, and garbage, we did what any other bunch of crazed effects guys would do -- we went out in it and shot some footage! This is real wind, and real dirt. You won't find realer than this. We have the damaged lungs to prove it.
The wind swirled around our shooting area, giving this footage a neat feel. And while we were at it, we separated out some of the chaff and shot that by itself, so you can use it to enhance other footage. It could also, in a pinch, probably serve as snow flurries.
Pre-keyed for ease!
