I never heard of the term until I started reading this board. When I see the term used, I understand it to be the practical light(s) in a given room or area. I figured this term was more applicable to documentary shooters. I consider myself a narrative filmmaker. As such, I will always try to have my image properly exposed using lights, silks, bounce boards, etc.
This is what I'm beginning to think. I could see very rare occasions could call for a creative choice to do so.
So there's a clear cut divide going on it looks like.
