I'm wondering how many footcandles to expect from 2K space lights spaced with 3 in the back and 2 further forward over the action area of a small stage. Its a green screen shoot with 2 -3 people in the shot head to toe. I would augment with front and sidelight of course. Just trying to plan properly for a shoot with a Red Epic.
I'm wondering if I could get away with lamping them down to 1K to save juice and make it easier to balance. Guessing I need around 25 footcandles or so.
I think the big question is how far are your lights from your stage. 2K lights give off an enormous amount of light, but distance-of-throw will diminish your footcandle reading radically. I'd suggest a simple test with a meter and some lights: turn on one 2K, move it to approximately the same distance you expect in the stage environment, and take a meter reading in an area about the size of your action space. Add another light, and do the same. Just make your lighting "wash" even for green screen.
