What's the most cost-efficient way to black out the floor of a black box? The director wants a shot of bare feet on the floor, but the floor needs to read almost pure black.
I'll be using an Octabank as a top source. We have a large solid I can lay on the ground, but I think it will still reflect some light and read as a milked grey. We can crush that later on, but I wanted to see if there was a way to get closer to the intended effect in-camera without messing with contrast/exposure later.
Velvet would be perfect, but very costly to get a large piece of (think group dance scene). A matte charcoal black paint might work also, but painting is off limits in this studio.
