About the style of movies and videos! !
Are those two upstairs talking nonsense? If you don't understand and don't insist, simply explain the reasons for the picture gap. Professional film shooting is film production, and chemical imaging is on the film, which is a real direct-shot picture with soft and rich colors; General DV cameras, including professional cameras below broadcast-level high-definition camcorders (about 10W), all adopt the principle of tricolor imaging, that is, digital imaging, so the videos taken by these machines are all made of tricolor small squares, so the picture contrast is high, not as soft as film, and the picture is much more watery than film. Post-production can be saved if it is given to an experienced editor, but it can only be saved a little, and the gap can still be clearly seen. As for the gap between the past and the present, it is inevitable, and the film quality is different. If you shoot with DV and mobile phone, it goes without saying that if you switch to a professional cameraman, it will also have a bad picture effect. DV can only be used for weddings and documentaries. Want the effect of film machine, at least use digital film equipment, generally a set of at least hundreds of thousands. As for the difference in picture style between science fiction films and reality films, it is because of the style problem. The 3D special effects designed by the production designer and directed by him are bound to be somewhat different from ordinary film pictures, but the soft colors of the pictures are better than those of DV machines, but the difference is that HDV can produce high-definition effects.
