Screen photography is the use of mobile phones to capture movie content while watching movies. A senior film promoter in the industry clearly expressed his opinion: "Screen photographers actually do more harm than help to film promotion" Some netizens believe that what they shoot and disseminate is what they think is the most exciting content of the movie, and these content are sometimes not included in the materials provided by the movie promoters.
The reason why movie promoters have to spend money to hire people to take stills and make posters, and also use various scientific and technological means to correct these materials, is precisely to use the best effect to present the excitement of the film.
