Forgot to post about this cool innovation by Gaffer RM- I needed a perfect ellipsis behind my subjects, so we hid an ETC 750W source four right behind them and RM had masterfully cut an oval pattern in a piece of galvanized metal- we added a couple of layers of light opal to the head, a bit of Soft FX diffusion to the lens, and shot a T2-2.8 split, providing just the right spread / falloff from white to grey. Patterns can be custom designed and printed by Rosco, but there was no time from the survey to the shoot- a little bit of cutting and testing produced great results again.
