Like David said a lot can be done with natural light and some reflectores. Per is the expert on natural lighting with reflectors. He can change the mood just by switching from silver or white to a gold reflector. Then there are things you can do with a small reflector as compatred with a large one. If you make it to Zion even for that first weekend, I know Per will be demonstrating it completely again. LOL, I am a visual person who understands better when I see it demo'ed.
