At the beginning of "IMAX: Hubble 3D", filming the process of "Atlantis" liftoff, the director arranged several cameras to ensure that the perfect shot required was captured in one shot. The Hubble Telescope itself carries sophisticated infrared and ultraviolet cameras, which capture a large number of pictures from the depths of the universe, which are then visualized by the supercomputer at the Space Telescope Science Institute in Baltimore, and then presented in a dynamic form in the film. 3D image

In order to prevent cosmic rays from adversely affecting the operation of the camera and ensure the shooting effect, the film crew made a lot of modifications to the IMAX camera. Although the built-in film up to 1 mile (1609 meters), the actual shooting time is only 8 minutes and 30 seconds. This places high demands on the astronauts who are on the plane. To this end, Tony Meyers and her team conducted up to eight astronauts in NASA's Neutral Buoyancy Laboratory. monthly training

After the plane was in space, most of the scenes in IMAX: Hubble 3D were filmed by astronauts on the "Hubble" maintenance program called "STS-125." Before liftoff, the astronauts received 25 hours of IMAX training at NASA's Johnson Space Center, where they mastered all the shooting skills. On May 11, 2009, a batch of IMAX 3D cameras to film the film was launched aboard the space shuttle Atlantis. Astronauts used them to film the five spacewalks needed to repair and upgrade Hubble. Astronauts also take pictures of the interior of the cabin from time to time, and these pictures are then processed into 3D pictures, so that the situation of zero gravity floating has the depth of 3D pictures. Because the shooting position is above the earth's atmosphere, the image will not be disturbed by atmospheric turbulence, the viewing is excellent, and there is no background light caused by atmospheric scattering, and the ultraviolet rays that will be absorbed by the ozone layer can be observed, so the visual effect is very good. However, the filming process of this part is very complicated, only 12 to 15 seconds of footage can be shot at a time, and there is no way to repeat it, so these footages are very precious. Due to the limited energy of the film and the astronauts during the shooting, the entire film did not last long
