Double Negative used survey data from sets and camera positions captured with a Leica Total Station. Some locations and the interior of the RV were LIDAR scanned. “An HDRI lighting pass was also taken for every set-up,” adds Couzens. “On other occasions witness cameras were used to record more complex moving lighting situations. And the mysterious Winklefix (an angle measuring tool) made many appearances while shooting inside the RV.”

Almost all of the scenes inside the RV were shot on a greenscreen stage. “The size and number of windows and reflective surfaces in the RV and the unrepeatable nature of road footage required us to capture large arcs of the driving background in one go,” says Couzens. “For this, the grips and camera department designed and built a purpose-specific six camera mount on a camera vehicle. It comprised of three Libra heads each mounting two cameras. Remarkably, the camera car was able to drive fast enough in forward or reverse gear, sparing any need to change the camera mounts between set-ups. This also enabled a near 180 degree overlapping field of view to be captured in one take.”

“These interlocking frames,” continues Couzens, “needed to be synced with a bloop-light, de-lensed, stabilized and stitched together in post before being projected onto a sphere or planar surface, re-lensed, graded and composited into the green-screen of the RV plates. Dust and dirt was added where needed. It was a considerable and necessary amount of work in 400 plus shots that hopefully the viewer never really notices!”
