There is no need for dry ice.
White background is white paper roll dropping from the ceiling. You can even make it drop from C-stands/light stands.
You can either shoot a white background in a large space and then you don't have to exclude boundaries, because the space is going to be large and everything in view of the camera will be white.
The excluding boundaries thing comes into play if you don't have access to a large space. Then you do the things in the small space, and there will be other things in view of the camera, but later in post production you cut it out of the shot and put a matching computer generated background in the places you cut out.
Hope that makes more sense.
Anyway. You don't have to understand everything. You just need to know what's possible. So when you interview someone, you have some idea of how to direct the questions.
I interviewed a sound guy today. I know nothing about sound. But just because of what I read here, I asked him a couple of questions and I understood his particular workflow, and what he cared about and what he didn't care about, and I realized that this person was not for me. He knows much more about sound that I do, but I understood enough to know, that somebody else I interviewed was better suited for me.
So again. Don't beat yourself up about not getting everything. Just know what's possible. It'll help you evaluate potential candidates better.
Cheers.
