"Earth at Night in Color" was filmed with 72 shoots over an 18-month period. However, the crew only filmed six days per month to take advantage of the full-moon light. That meant there would be six to eight simultaneous shoots taking place across the globe.
Using various combinations of astronomy-grade glass and low-light cameras, "Earth at Night" crews shot the full spectrum of light from (visible) white light to (invisible) infrared light. They then teamed up with a company that specializes in film restoration, NULIGHT Studios, and stripped out the pink and the red.
To capture bears and the northern lights with little light pollution, a cameraperson had to drive out to the wilderness and cross country ski more than 20 kilometers in the freezing cold
"Earth at Night in Color" is the first production to film Peregrine Falcons at night.
Next-generation cameras reveal the nocturnal lives of animals across six continents, from the Arctic Circle to the African grasslands.
