I haven't worked with smoke/haze/fog before and I'm interested in learning the best way to create atmosphere on a set that's safe for actors/crew who may be asthmatic or very sensitive. In your experience, what's the best way to go? Smoke machines? Fog machines? Oil based? Water based? Any special non-toxic, non-allergenic formulas? Any secret tips to creating the effect in the safest, most pleasant way possible for cast and crew to be working in?
Thanks so much!
