This set up was the exact set up we ran with all day. The only fixes from shot to shot were either moving Neg closer or further away because the edge of the frame had changed or by thinning out the sheers on the window for the same reason.
2 x M40s for the back window and BG. 1 x M90 for the Mid ground and then 2 Vortexes through 8x8 for the inside wrap. The practicals played on and there is a wall of black frame left to help get an contrast we could.
