How is the effect of zero gravity photographed?

The so-called zero gravity effect should refer to the photographic effect that the person or thing being photographed is not attracted by the gravity of the earth, but is suspended in the air and slowly moves (that is, weightlessness).

Because the movement of objects in weightlessness is generally slow, people's movements will be slow. If the weightless photography effect is achieved under normal gravity, it is a feasible method to take photos at normal speed and then play them slowly to reduce the moving speed of objects in photography.

In order to achieve a more realistic simulation, it is suggested to shoot the subject in a real weightless state.

Under the premise of not entering space, a passenger plane or transport plane can be used for parabolic flight to realize weightlessness. The modified Il -76 training machine can fly 20 to 30 parabolas in one take-off and landing, and each parabola can produce weightless time of about 25 seconds.
