Russell Carpenter, ASC: Lighting the world of Fire and Ash

The Cinematography Podcast Episode 344: Russell Carpenter When cinematographer Russell Carpenter began working on Avatar: The Way of Water and Avatar: Fire and Ash concurrently, he knew stepping into the world of Pandora would be a much different production environment. Carpenter and director Jim Cameron had previously collaborated on True Lies and Titanic, which won him the Academy Award for Best Cinematography. As the cinematographer, Carpenter’s primary concern was ensuring the lighting on live, motion-captured actors blended seamlessly with a CGI-generated universe. Audiences instinctively understand the physics of sunlight filtering through a forest or the way light refracts underwater. To maintain an emotional connection to the story, Cameron insisted that every frame feel like it was in the real world of Pandora. The Avatar sequels were built in layers, with digital artists building the environment based on the script. Rough versions of the scenes and the blocking for the actors were plotted out, and then they were ready for the motion capture with the actors. Carpenter worked closely with production designers to determine how light should "feel" in these virtual spaces. Because the background was digital, the camera movement and lighting could be tested with instant feedback. If a virtual camera moved through a forest, the real-world lighting on the actor could be tested to react to every digital leaf and shadow in real-time. For over a year, Carpenter lived in two worlds: the virtual and the physical. "I had to keep lighting consistent in the CGI world while translating what Jim was doing on the capture stage," Carpenter says. "In the world of motion capture, things have to match to the half-second. If the camera travels a specific distance at a specific speed, the actor has to be exactly there. It’s painstaking." A major breakthrough for the sequels was the use of programmable LED systems. Working with computer programmers and moving lights, Carpenter’s team devised a way to shift intricate lighting setups instantly. This allowed for more complex visual storytelling, such as backlit sequences and the dappled, moving light of the Pandoran jungles. For Avatar: Fire and Ash, Cameron pushed for a more "organic" look, requesting the digital world mimic the flaws of physical film cameras. “Certain artifacts were introduced into Fire and Ash that we didn't quite have on Way of Water,” Carpenter explains, “such as lens flares and the appearance of water running off the front plate of a camera lens.” The team tested shooting lens flares, and a Weta programmer built it into the CGI world. To simulate the "Ash People" shooting flaming arrows, Carpenter’s team used a grid of overhead LEDs programmed to "zip" past the actors' heads at arrow-speed, creating a realistic flicker of firelight on their faces Despite the technical hurdles, Carpenter found that the core of his craft—sculpting light—remained the same, even if the toolkit had changed. He admits the transition isn't for everyone. “I would say to any cinematographer who ventures into this territory, there's a learning curve where you definitely feel like a stranger in a strange land,” he says. “You realize that, especially in terms of live action, your percentage of the pie is less—but your impact on the final vision remains vital.” You can see Avatar: Fire and Ash in a variety of formats in theaters everywhere.
