The effect of film shooting method.

The image quality taken by film camera is much higher than the other two methods. The digital film can avoid the aging and fading of the film caused by light source irradiation, ensure that the film will always be as bright as new, ensure that the picture has no jitter and flicker, have enough pixel stability, and the audience will never see scratches and wear like raindrops again. In addition, the release of digital film programs no longer requires a large number of printing films, which not only saves production costs, but also benefits environmental protection. With the guarantee of digital transmission technology, the quality of the whole film will not be lost in the transmission process, so that the audience can see the film exactly like the film director. In other words, once the digital movie signal is sent out, no matter how many digital cinemas there are on the earth, the same program can be shown at the same time. At the same time, digital projection equipment can also provide value-added services for cinemas, such as real-time broadcast of major sports competitions, cultural performances, distance education and so on. And make it the trend and direction of development in today's world.
