When it comes to museums, I believe everyone thinks of various cultural heritages with a long history, such as the bronze statue of Four Sheep, the Riverside Scene at Qingming Festival, the Terracotta Warriors and Horses of Qin Shihuang and so on. But have you noticed? Some cultural relics in these cultural heritages are forbidden to take pictures. So why is this?

First of all, people who have been to the museum should know that the light in the exhibition hall of the museum is generally very dark, partly because it is actually to protect cultural relics. Because there are some organic cultural relics in the exhibits of the museum, these cultural relics are generally sensitive to light. If you are exposed to harmful light for a long time, photochemical action will easily occur, which will lead to the fading, yellowing and fracture of the collection and eventually damage the cultural relics.

Why is it forbidden to take pictures? The reason is to avoid this harmful light. In theory, almost all light will cause damage to cultural relics, especially ultraviolet and infrared rays will cause structural damage to the instrument surface. For example, when Qin Terracotta Warriors and Horses were first unearthed, many ice surfaces were painted, but they soon fell off due to temperature, humidity, light, environmental protection and other reasons. It is reasonable to say that normal shooting will not damage the product, but the problem lies in the flash. According to the lighting design specification of the museum, for some exhibits that are particularly sensitive to light, the illumination should be less than 50 lux, those that are sensitive to light should be less than 150 lux, and those that are not sensitive to the other side should be less than 300 lux.

But you know what? The instantaneous illumination of the camera is as high as 8000 lux, which has far exceeded the illumination standard. The curator of the Insect Museum said that after more than 500 flashes, the color of insect specimens will fade 10%-20%, and after more than 2,000 flashes, the standard color will fade by more than half. Therefore, from the perspective of protecting cultural relics, museums are generally listed as prohibiting the use of flashlights.

However, in order to avoid unnecessary regulatory problems, some museums even ban filming directly. In addition, in addition to the protection of cultural relics, part of the reason is to enhance the experience of tourists. Generally, there will be many people taking pictures at some popular exhibitions. If everyone stops to take pictures, it will seriously affect the order of participation and cause congestion. Moreover, some photographers will choose various tricky angles when shooting, which is more likely to cause cultural relics damage or personal injury.

So filming is forbidden, in part to control the operating costs of the museum. In short, of course, there are reasons why the exhibits can't be photographed. As spectators, we should abide by the rules, not exploit loopholes. Besides, instead of recording the charm of art with clicking again and again, isn't seeing believing?
