DP Russell Carpenter on the Virtual Reality of ‘Avatar: The Way of Water’ - Film School Rejects

We chat with the cinematographer astir the challenges of simultaneously shooting live-action and virtual.

Welcome to World Builders, our ongoing bid of conversations with the industry’s astir productive and thoughtful behind-the-scenes craftspeople. In this entry, we chat with cinematographer Russell Carpenter astir Avatar: The Way of Water and however modern cameras made the intolerable possible.

Weeks earlier accumulation began connected Avatar: The Way of Water, Sony unveiled their Venice camera package, allowing unparalleled flexibility successful which filmmakers could cram their shots. The optical artifact is separated from the camera and mounted connected a lightweight 3D rig astatine a region of up to 20 feet. James Cameron and Sony person a precise choky relationship, and the institution was anxious for the manager to trial retired their babe and propulsion it arsenic acold arsenic they knew helium could.

Cinematographer Russell Carpenter abruptly recovered himself moving a strategy that squeezed into choky areas that his 2D cameras connected Titanic and True Lies would ne'er fit. The camera could run adjacent to the actors’ faces, breaking the affectional region often created successful 3D ventures. Cameron, who often prefers to beryllium the 1 slinging the shooter, was besides capable to stay adjacent the performers.

In addition, Sony and Cameron wanted to sprout 48 frames per second, which is treble what audiences usually acquisition cinematically. With aboriginal entree to the Venice package, Carpenter could test, test, test. He fell hard for the camera’s mobility, but helium was arsenic enamored with its dynamic scope and colour depth.

“We spell backmost to Jim,” says Carpenter, “and we amusement him our test. He says, ‘Yeah, yeah, I get this.’ We’re moving with a 3D strategy that is inherently going to, astatine least, instrumentality a halt disconnected the airy that yet gets to the sensor. But, also, we are present shooting astatine 48 frames per second. So, there’s different reasonably important nonaccomplishment of light.”

Their lighting plans had to alteration connected Avatar: The Way of Water. Carpenter’s lighting technician, Len Levine, projected a method of moving the lights via distant control. As such, they could marque adjustments instantaneously, shifting not conscionable their absorption but their quality, color, and intensity. The precision and velocity were a game-changer, and it came from Levine and Carpenter visiting Cameron portion helium was moving successful the virtual world.

“Jim’s successful a strategy wherever helium has an astonishing magnitude of control,” helium says. “He’s possibly got 23 radical astatine computers. So, if helium says, ‘I request that Na’vi conscionable a small spot tinier,’ and the framing doesn’t work, ‘let’s determination him conscionable a small spot to the near and lower. Oh, hey, that waterfall isn’t rather moving for maine there; let’s determination it 2 feet.’ We were watching this, and we were going, ‘Look astatine the flexibility helium has! We person truthful galore antithetic scenarios to woody with; however tin we springiness him thing similar?'”

Considering the airy root connected Pandora is much analyzable than your accustomed environment. The satellite itself shines, smashing assorted colors unneurotic during astir each series successful the film. Without Levine’s thought of lighting, the accumulation would beryllium 10 times slower, if not 20 times slower.

“For instance,” Carpenter continues, “the Na’vi wood is afloat of things that are bioluminescent, a batch of green. The airy comes through, strikes those, and past it comes up to, say, an histrion walking done the wood oregon moving done the forest. It comes up, and you spot a spot of greenish connected the histrion arsenic helium runs done this spot of light. Instead of putting much lighting down connected the floor, we would really conscionable enactment bounce cards down there, possibly ample bounce cards. We could get precisely the close colour successful the close place.”

Shooting the stages was lone fractional of Carpenter’s job. The different spot existed successful the integer domain. He would sprout a chunk successful live-action, past spell to his machine set, and past backmost to live-action.

“One of the things I was tasked with close away,” helium says, “was supervising the virtual lighting. Jim was retired on the Volume, and helium was mounting up and blocking his scenes; helium was moving with his cameras. I’m successful different portion of the building. I’m moving with a fantastic squad of lighting designers, radical who cognize CGI. I had to larn to thrust the bicycle very, precise quickly, the CGI lighting thing.

Carpenter worked with Gazebo, Weta’s in-house rendering bundle that uses real-world physics to surmise however assorted surfaces would respond to circumstantial lights. The cinematographer credits Visual Effects Supervisor Dan Cox with making the ocular sprout a one-for-one acquisition with the unrecorded shoot. Although successful the virtual realm, helium could manipulate the sources successful ways helium couldn’t successful reality.

“Somebody would flip a switch,” says Carpenter, “and the airy would disappear, basically. You wouldn’t spot it. You’d conscionable spot the effect of the light. It was a batch of fun.”

For Carpenter, portion of that amusive was adjusting his Earthbound notions of cinematography. He was moving successful an alien world, inspired by terrestrial locations but pushed to an extremity. The past happening helium wanted assemblage members to admit was their mundane concern encounters with precise agleam lights.

“The satellite of Pandora is decidedly antithetic from the satellite of the RDA human-made things,” helium says. “RDA lighting is similar walking into a large container store, a Home Depot. It’s abrasive, and it’s not a batch of amusive to beryllium around, where, of course, Pandora is conscionable this wonderful, nuanced, multicolor imaginativeness that Jim had. His mandate was, there’s a batch of colour here, and I privation you to commencement pulling the airy apart. He said, ‘When you get to your sunset scenes, retrieve conscionable commencement to fracture the light. Think of the things that Maxfield Parrish did successful his work.’ The happening was, I knew aboriginal on, particularly successful the scenes with Spider, I’d person to lucifer what I did with those fantastic radical connected Gazebo.”

Continuity proved challenging, but possibly not arsenic large a situation arsenic Carpenter initially feared. Those Weta geniuses had his back, keeping way of immoderate huffy wizardry helium was cooking up successful their labs. When changes connected acceptable didn’t align with what he’d already completed successful the virtual stage, they could set reasonably quickly.

“The fantastic happening astir Gazebo,” says Carpenter, “as opposed to what they had to enactment with connected the archetypal Avatar, is it virtually tracks everything you did. You cognize the colour temperature; you cognize precisely wherever the airy was and wherefore you did it. You person each those breadcrumbs that pb you backmost to your archetypal imaginativeness erstwhile you were lighting. All that accusation goes on done the scenes. If Jim decides to marque a alteration successful however he’s blocking a scene, well, the lighting accusation is inactive there. If helium does a antithetic shot, the lighting information’s inactive there. That was a large thing.”

With truthful overmuch absorption connected Avatar‘s integer creation, Carpenter doesn’t privation the speech astir the movie to autumn exclusively into the virtual. He took James Cameron’s marching orders to heart. Pandora is alien, and the Na’vi are alien, but they’re yet our reflections. Separating the existent from the unreal misses the constituent and is wholly intolerable erstwhile you look astatine however they accomplished the movie.

“You person to retrieve that everything successful this movie is based connected thing real,” helium says. “You really had existent radical successful sensor suits with underwater question seizure systems. They’re doing everything. There wasn’t 1 happening that was like, ‘Well, we’ll conscionable invent this creature.’ You had the Tulkun, that’s based connected watching however whales move. Any carnal is not immoderate brainsick concoction that idiosyncratic came up with astatine a CGI workstation. It’s each based connected thing real.”

When the assemblage stumbles from the theater, the cinematographer wants them to deliberation astir their surroundings. He doesn’t caput them having a formation of fancy, letting their imaginativeness drift upward to the acold reaches of space, but helium hopes that they admit the overseas arsenic the home erstwhile they bent retired connected those fictional shores.

“Pandora truly does basal successful for however things are connected Earth,” says Carpenter. “Light and each kinds of carnal things and gravity, they’re the aforesaid arsenic they are connected Earth. That’s the touchstone.”
