What kind of damage will taking photos in the museum do to cultural relics?

Flash lights come and go, and it is often heard that the staff in black in the exhibition hall say, "Please don't take pictures with flash lights." "This exhibit cannot be photographed." "Would you please stay awake?" This last sentence is hard enough. Working as a staff member in such a scene is a very hard job, which always throws cold water on the enthusiastic audience. And it's backwards and forwards. When the old man is away, he must spend money to buy a new one.

I saw some discussions about taking pictures in museums on the Internet. There are three main reasons why you can't take photos: (1) copyright protection (2) cultural relics protection (3) affecting the exhibition atmosphere.

(1) About copyright protection. To be honest, because of copyright protection, there are few cases in China where photos can't be taken, especially in formal exhibitions in museums. The first Expo, as well as major museums and regular exhibitions in Shanghai, can be photographed. Indeed, there are almost no restrictions on taking photos in the Louvre in Paris, and the flashing lights in front of the treasures of the three major town halls scratch people. However, when I went to the Prado Museum in Madrid last year (one of the three key museums in Madrid), I couldn't take any photos anywhere in it. As long as someone raises the camera, someone will come out immediately to stop it. In my opinion, whether the copyright is protected by prohibiting taking pictures cannot judge whether the museum system is advanced or not. Although the open system is very popular with the audience, it is completely reasonable to have special copyright protection requirements for some special exhibitions, such as exhibitors.

(2) About the protection of cultural relics. It mainly means that you can't take pictures with flash, otherwise it will damage cultural relics. It happened that Beijing TV had a little program about visiting museums, which happened to be shot on the first blog. It says "It's uncivilized to take pictures with a flash": it hurts cultural relics and affects others. What I am curious about is what kind of damage flash will bring to cultural relics. I found a passage from Professor Wu Shikang (Professor of Institute of Photosensitive Chemistry, China Academy of Sciences) on the Internet: "The wavelength of ordinary visible light is between 400 nm and 700 nm, and the ultraviolet energy below 400 nm is very large, which is easy to be absorbed by objects, thus deteriorating objects; Infrared energy above 700 nm is small, so it is not easy to be absorbed by objects, so it is very safe. Wood, plants, silk and other substances are all polymer structures, containing cellulose or protein, which are easily deteriorated and damaged by light, electricity and bacteria; Other substances, such as stone, copper, iron and ceramics, are not easily affected by light. We use different models of flashlights, with long and short wavelengths. But they should all be visible light below 700 nanometers, which is more or less harmful to cultural relics with polymer structure. Therefore, wooden buildings, calligraphy and painting, silk fabrics, murals and other cultural relics should be prohibited from taking pictures with flash. " Plus the terracotta warriors mentioned by the video experts below.

It can be seen that not all cultural relics are afraid of flash. But it is difficult for the audience to remember which cultural relics cannot be "discharged". So for the museum, the simple "no photos with flash" is the most effective.

But the problem is that many people use flash, not intentionally. Some forgot to turn it off; If you don't open it, you can only take a paste, and you are in a hurry to take pictures, so you turn on the flash. The original intention of the program of Beijing Radio 9 is very good, but I'm afraid it's hard to restrain the excitement and impulse of the audience by saying "Don't turn on the flash" on TV.

How to solve this problem? In my opinion, instead of telling the audience "how to take a good photo without a flash", it is better to tell the audience "why not turn on the flash". After all, "taking good photos" is what the audience is most concerned about. I don't know much about photography, but I also know that under the lighting conditions like museums, photos without flash are often better. In order to prevent hand shaking and blurred photos, you only need to find a stable object to support when taking photos, such as the counter of a display cabinet (glass cabinet) or the head or shoulder of a friend, to ensure the photo effect.

(I usually put the photo mode in P file, and the above method is basically enough. I'm not sure if I'm completely stupid about cameras. Maybe we should set it to night mode? If you know the situation and have other effective tips to take good photos in the museum without flash, please be sure to let me know next time. )

So when should we tell the audience this little trick? As far as yesterday's first blog is concerned, it is the best choice to use the audience's queuing time. 15 minute queue time is boring time and also the warm-up stage of the exhibition. As long as you put a sign next to the line every once in a while introducing "the harm of flash" and "how to take good photos without flash", you will definitely have a good reading rate. We can't expect this brand to completely solve the problem of flash, but at least compared with the tit-for-tat between the staff and the audience, this brand is much warmer from the perspective of cultural relics and audiences.

(3) Finally, briefly talk about the problem that taking photos affects the exhibition atmosphere. Personally, I don't like the flashing lights and clicks in the dark environment of the museum. Although the museum is a public space, watching the exhibition is a particularly private matter, which requires a quiet and peaceful atmosphere to "concentrate on dialogue" with the exhibits. In addition, people who only know how to press the shutter when watching an exhibition, in my opinion, are people who don't know how to appreciate the exhibits attentively, and look at the exhibition with a utilitarian mentality, just seeking possession. If there are many such people in a museum, I either choose a day with few people or prefer not to see it.
