Because IMAX adopts large screen, large slope (the height of each row of steps in the audience hall is 0.45m) and large film (70mm 15 perforation), the picture definition is extremely high, and it is equipped with 6-channel stereo, which has great audio-visual impact and makes the audience feel immersive. Combined with 3D, it is no wonder that some people shouted the slogan "Let the home theater die" after watching IMAX movies.
If only "big" was the selling point, IMAX movies would never have so many fans. It can be large while maintaining high definition. After the conversion, the coarse particles on the film disappear completely, and the outline edge is clearer, and even the pores of the actor's facial skin can be seen in the close-up. Moreover, the 3D version of IMAX movies makes the audience feel as if they are in a real scene.
