One of our clients is a fog machine manufacturer, and working with them made me realize the importance fog has in the entertainment industry. You don't realize it, because fog is rarely supposed to be the star of the show but rather a support for other effects.

I also did not know that there are different qualities of fog... I thought fog is fog, but it seems that some fog machines are really better than others. One of the aspects of fog quality is being able to breathe even when there's lot of it. One one occasion, we fogged a studio so much that I could not see my own hand 6inches from my eyes, and I was still breathing normally as if the air war pure. I couldn't say if it has long-terms effects if you breathe too much of it though, but I can say that not coughing with so much fog is quite impressive.

Also, don't get caught speaking of "smoke" to these people, who take a lot of pride in their product :) It's fog and haze... not smoke!
