The futuristic cyberpunk universe of the Netflix series Altered Carbon is as visually stunning as it is colourful, due to the vision and skill of the show's Directors of Photography (DOPs) Neville Kidd and Martin Ahlgren. Here, Neville explains how they created the moody yet vibrant feel of the show, shooting in 5K with Canon Cine prime lenses.

Imagine what the world will look like 350 years from now. If it's anything like the premise of the sci-fi show Altered Carbon, the wealthy will inhabit the clouds, their palaces illuminated by beautiful natural light. They'll live for hundreds of years, yet look young and beautiful, regularly transferring their digitised consciousness to the best new bodies to come onto the market. Meanwhile, the other 99% will be stuck down below, in dark, dingy spaces lit by holograms, neon signs and moving traffic in the absence of sunlight.

This was the universe that Neville and Martin were tasked with visualising, based on screenwriter Laeta Kalogridis' interpretation of Richard K Morgan's 2002 novel, Altered Carbon. The two worlds, in the clouds and down below, required completely different approaches both in terms of the filming and lighting. In the clouds, they used remote-controlled telescopic camera cranes and soft natural lighting to portray the world of the wealthy. Meanwhile, on the ground, where the so-called Grinders live in gritty streets, they used handheld cameras and hard light to accentuate shadows and create a feeling of tension.

"We needed a combination of light sources coming from adverts and holograms," Neville explains. "We decided that in the future, a lot of advertising would come from holograms in the streets trying to lure you in and sell you stuff, so we needed to create the interactive lighting effects for the holograms.

"For us, there is a very close relationship between where all of the visual effects are going to be and where the tracks of light need to be. A lot of planning went into all of the shots so we could constantly sell the futuristic world of advertising and the glow of the rich people above, compared to the sort of darker world of the poorer people below."

Working at close range

The 10-episode first series was shot in 5K using a variety of Canon Cine lenses offering focal lengths of 24mm, 35mm and 50mm. These versatile lenses are engineered to meet the high standards of cinematographers shooting high-quality 4K television and movies.

Neville and Martin used the CN-E50mm T1.3 L F, CN-E24mm T1.5 L F and CN-E35mm T1.5 L F lenses for Altered Carbon, the latter most frequently. "The 35mm lens was a nice wide lens that wasn't too wide for faces, so there was no face distortion and it had a lovely quality to it. Plus, being a fast lens, fall-off was gorgeous," says Neville.

Another benefit of using Canon's Cine lenses was the ability to achieve focus at very close range. "The close focus of a 50mm Cooke lens on a 6.5K camera is 112cm, which is too far away. So we took advantage of the Canon primes' ability to give us close focus [of 30-45cm], which is your standard close focus range," Neville explains.

Getting the effects in-camera

"If we had green-screened everything, it would have ended up costing a lot of money over 10 episodes. The basic problem you have with Altered Carbon is you are not making a two-hour movie, you are making a 10-hour show. So you've got to consider the cost implications over 10 hours," he adds.

It was also beneficial to the bottom line that the Canon Cine prime lenses were able to open up to a wide aperture, allowing Neville and Martin to save on additional lighting. "The Cine primes are fast lenses, which helped us enormously," Neville says.

"Vista Vision lenses are slightly slower and when you are doing episodic television you need a faster lens so you can get the amount of lighting required. Typically, you shoot with a combination of T4, T2.8 and everything, and some of the Cine primes open up to T1.3. That's a lot more light, so that really helped."
