Ah. Got the ratio. I had 2 hot lights on either side of her and the hairlight. They have two levels - on or off. Anyway, I have some wiggle room but not much the room is 10'2"x12'4". I only have a few options with angles due to door ways. Luckily the rail circles around about 2 feet on either side so I might be able to adjust. We may add to this to cover the front window at some point. Maybe I can get my lights suspended next so I have a little more floor space.
I will experiment with angles. This was good info, THANKS!
