What camera should I use to take pictures of museum exhibits?

Advanced Technology for Shooting Museum Exhibits (ZT)

Generally speaking, the lighting fixtures in museums are relatively dim to protect the exhibits. If you shoot with a digital camera, you will usually use a flash to assist, so how to avoid overexposure and whitening of the whole exhibition? This article will discuss this.

Usually, in order to avoid the reflection of glass, experienced photographers will use the polarizer attached to the camera lens, which can really play some roles, but what if they don't bring these devices or buy a polarizer when traveling? Here, the author will only explain to you how to avoid the overexposure of the picture and the reflection of strong light on the glass when shooting with a flash in a dimly lit exhibition hall.

Some people may think that it is useless to use flash lights in museums, because most of the exhibits are usually placed in glass display cases. When the flash flashes, the reflection caused by the glass will form a reflection on the glass surface. And they think that for such a large exhibition hall, the flash is even more useless to the hero. But there are exceptions to everything.

One of the shooting methods: First, you decide which exhibits to put into the picture to be shot, then you carefully choose a position that forms a certain oblique angle with the window glass and the exhibits, and then operate the camera to zoom and focus, and try to position the exhibits in the center of the picture, because you may need to shoot some explanatory boards or text descriptions on the side or behind the exhibits.

The second shooting method: frontal shooting, also using flash, at this time you need to put the camera in a higher position to shoot those exhibits. Of course, the principle of avoiding reflection is the same as the photo 1, which skillfully uses the relationship between incident angle and reflection angle.

There is an included angle between the camera and the display window glass, so that when the shutter is pressed, the strong light of the flash hits the window glass, but does not enter the capture range of the lens, thus avoiding the interference of the flash on the glass. There is a slight reflection on the glass behind the exhibition, but as long as we continue to improve the position of the camera, that is, change the incident angle of the flash, even this slight reflection can be completely avoided.

The third shooting method: take a photo of a metal exhibit without glass protection, because the metal cultural relics themselves can easily reflect the flash of the camera flash, so it is necessary to keep a certain height between the photographer and the exhibit, which is very high. At this time, after the shooting distance is far away, the output of the flash on the corresponding camera will also decrease with the increase of the distance. For example, the suggested maximum effective range of the flash on the camera used by the author is 0.3 ~ 2.5 meters, so at this time, one.

Finally, the author gives you a summary. In order to successfully and perfectly photograph the exhibits in the museum, everyone needs to be familiar with the relationship between angle and reflection. I believe that people who have achieved good results in the physical optics examination in middle schools can quickly understand how to avoid reflective shooting at this time. However, as long as you practice in front of the glass at home in advance, you can quickly master this essentials. In addition, it is necessary to emphasize the kung fu of holding the camera. Holding the camera steadily is another prerequisite to ensure the success of shooting.

In most cases, many unearthed cultural relics are afraid of direct exposure to strong flash, because strong flash may damage the surface of cultural relics, which is why most museums are not allowed to use cameras to shoot exhibits. Then, out of love for these precious cultural relics, if possible, I hope everyone will try not to shoot with flash.
