I would love some advice for this one...
I have an upcoming shoot on a 2-walled white cyc. We are shooting 6-7 people sitting in chairs and a couch in the middle of the stage. The director wants the talent to be evenly, soft light but the cyc walls behind and to the sides of the them to have a gradient tone to them to show a sense of space and not to feel the infinite white world.
cyc is 30'x60' and 16' tall. Their is a 20'x40' diffusion (not sure what material exactly) over top and a grid of space lights (2k i think) going through the diffusion
Their are also additional space lights along the back edge for the walls.
My plan was to try and use some of the space lights in the diffusion for the talent but not the back lights for the wall. But since it's such a huge diffusion I'm worried about spill.
I was thinking i could black out all around the diffusion to direct the light more and than add something to create the gradient along the walls. But would that be to much trouble to try and work in that much black?
Would I be better off flying in my own soft toplight for ambient fill. Maybe some Chimera pancakes?
Also, If I get the ambient light bouncing of the white on the floor and creating a nice spread will I also need some kind of front key/fill? That again, worries me about spilling on the background
I'd appreciate any ideas
