Why not shoot lianzhi in the back garden of the Forbidden City?

Because the flash emits visible light, it also emits infrared and ultraviolet light. Just as ultraviolet rays in the sun can cause harm to the skin, the visible light and invisible light emitted by the flash can also cause different degrees of harm to cultural relics.

According to Chengdu Evening News, infrared rays have a thermal effect, which will destroy textile fibers, change dyes and pigments, and lead to the fading of cultural relics. In addition, oxidation is also the chief culprit in destroying cultural relics. Under the illumination condition, light provides energy for oxidation reaction and accelerates oxidation.

1. No shooting to improve the tourist experience. People who love art will often visit museums and even become members or recommend them to more friends. When a group of people are shooting works of art with selfie sticks, it is difficult for others to calm down and seriously appreciate the works. Sometimes, more people shoot a work of art, which will cause traffic jams.

No photos can make people flow smoothly and ensure everyone's safety. To a certain extent, it also reduces the insurance cost of the museum, because some photographers will find a very special angle to shoot, such as taking pictures from the balcony. Reduce the chance of injury and make the museum run at a lower cost.

2. The prohibition of shooting makes the gift shop monopolize the copyright of the image. In this way, the books, posters and postcards in the gift shop have become the only legal sources of works of art and clear images of places of interest.
