How did this movie come out? Can it be made in outer space?

In the gravitational outer space scene, only the face of the actor under the helmet is actually photographed, which makes the film more memorable technically and aesthetically. Everything else in the outer space scene, including the spacesuit, the space station and the earth, is made by CG. Similarly, in one scene, Si Tong floats on a spaceship without a spacesuit. Brock is hung on the set by a steel wire, and her surroundings are digitally made. Most of the scenes in the space station were shot in the scenery.

Gravity has become an example in many ways, showing how to expand the role of the photographer in a film that contains a lot of virtual production. Admittedly, Lubezki has played an irreplaceable role in processing real shots and computer-generated images. In addition to conceiving the motion of virtual camera with Cuarón, he also designed virtual environment lighting for digital technicians, so that the light during real shooting can match the CG scene, and the final output result is as perfect as possible.
