I'm interested in experimenting with a fog machine in an upcoming shoot.
Fog machines that produce enough to envelope a whole model typically use glycol. (as opposed to desktop fog which often just uses dry ice) If you've been to my website you know I like to shoot nudes or near-nudes with flowing cloth and motion. I'd like to either add fog to the mix or replace the cloth with fog lit in various dramatic ways. My questions:
1. Numerous studies have found glycol fog to be safe, but some performers have found it irritates their throats or nose (because glycol is hydroscopic so it tends to suck the moisture out of whatever it contacts, e.g., in the nose and throat). How common, and at what concentrations does this become a problem?
2. Also, how much of a hazard is it for studio lights, cameras, lenses, etc? I've been told it can leave a residue (a thin slippery film) of glycol on things.
Thanks in advance!
