I can't believe it was just over a year ago that we were out shooting plates for Westworld. For the new season, they knew they would have scenes on a train and that the train car would be a standing set. Rather than shoot green screen and composite in later, they had us shoot the train plates ahead of time so they could do LED walls for interactive lighting.
Seeing as how they would be train height and potentially see out of multiple windows on any given side of the train car, we shot with 3 RED Komodos on Ronins (for smoothness) with 14mm Sigma Art primes, which would cover a 180° field of view with enough overlap to stitch the cameras together. These were all built on a truck at train window height with the run/stop synchronized via a Tilta Nucleus. By setting the Nucleus motor on each camera to the same channel, a single handset could control the iris (which we wanted to match between cameras) and run/stop on all three units.
