After developing a new DI stitching methodology for the Oscar-winning “Birdman,” Technicolor raised the bar for dealing exclusively with uncontrollable natural light on this year’s frontrunner, “The Revenant.”
This entailed creating another unconventional methodology for handling complex data management and color grading dailies on location in the Canadian wilds of Alberta, and then full color finishing in the production offices in Calgary and British Columbia.
“He was keenly aware of the issues that would bring about, and he wanted to be as prepared as possible. So we talked about that early on, as soon as he started doing scouting and conducting tests. I saw all that [test] material, and we would get together and play with it and establish preliminary looks. In fact, even before he shot a frame of this movie, Chivo knew what kind of pipeline we would have to set up, and he knew how long we would need for the finishing and that it would be a longer schedule than typical. We discussed the kinds of work we would be doing, and that we would be isolating and playing with different parts of individual frames. That was all planned out in advance.”
Thus, with limited “magic hour” daylight shooting (usually 9:30 a.m to 4:00 p.m.) in late fall and winter and shifting clouds and giant trees blocking and changing the direction of light and producing moving shadows, data management to editorial and the various VFX companies — including Technicolor-owned MPC, which worked on the early ambush, and ILM, which did the grizzly attack — had to be consistent throughout the entire project.
A team of finishing artists under Scott’s supervision color graded the imagery using Autodesk Lustre 2015 Extension 3 software and a Christie 4220 4k projector. Simultaneously, a team of 10 VFX artists under Spilatro’s supervision worked to hand animate mattes and use them to perform roto work on faces, bodies, and other elements photographed by Lubezki in order to assure that directional key light, backlight, or shadows were hitting exactly where he wanted and moving correctly in a natural, undetected way.
But Technicolor always built on the foundation of Lubezki’s original material to dig into his digital “negative” and re-balance it in precisely the way he wanted: manipulating light on location or on set, and giving him the flexibility he needed to make adjustments for dramatic purposes during the finishing.
Technicolor then created a master 4k DCP for the movie, while the Dolby master, award-season screeners, and home entertainment versions
were finished by colorist Skip Kimball.
“Our whole approach was conceived and based on what
Chivo said he needed to achieve and what Alejandro [González Iñárritu] and he
were envisioning,” Scott concluded. “We advanced the technology and our
thinking about how to do things so that they could be in the middle of the
process. That is a fairly new concept for this industry, but it is the best way
for the cinematographer to continue to guide the imagery, even after production
ends, and not to sit to the side waiting for ‘post’ to do its thing.”
