Why do cameras use tripods instead of quadrupeds?

A tripod, a bracket for stabilizing the camera. Consumers often ignore the importance of tripod when buying digital cameras. In fact, photos are often taken with the help of tripods, such as star track shooting, running water shooting, night scene shooting, macro shooting and so on. Whether amateur users or professional users, the role of tripod can not be ignored. Its main function is to stabilize the camera to achieve a certain photographic effect.

Some professional photographers often take a tripod when taking pictures, especially when shooting outdoors. Fixing the camera on the tripod can prevent the camera shake from affecting the imaging effect. So why should the camera be placed on a tripod instead of a tripod?

And then what?

The tripod is used to fix the camera. Because three points determine a plane, any given three points are on a plane. When you open the tripod, the three feet can match the three points on the ground well. It doesn't matter if the ground is uneven at this time, because when you put the tripod, you only care about the plane determined by three points on the ground where the three feet are located, and no matter how uneven the other places are, it won't change the plane determined by three points. Coupled with the stability of the triangle, the whole tripod stands firmly on the ground, and the camera fixed on the tripod is very stable and will not shake. As long as the focal length and aperture are adjusted, no matter how long the exposure is, the camera will not take blurred photos because of jitter.

If we use quadrupeds, when three feet are placed, the placement of the fourth foot will be affected by the uneven ground. At this time, it is necessary to adjust the length of the fourth foot so that it just falls to the ground. Because photographers often have to shoot in different places, and the ground conditions in each place are different, it is very troublesome to adjust the fourth foot every time they shoot. Three feet is enough to support the camera. Adding an extra foot has no advantage except adding trouble, so there is no need to use quadrupeds.

If it is on the flat ground, you can put a tripod or a quadruped and adjust the four feet of the quadruped on a plane. In fact, the tables and chairs at home are all four-legged, and some swivel chairs even have five or six feet. Generally speaking, the floor at home is flat. As long as the four feet of the table are placed on a flat surface, the table can be placed smoothly and generally will not move at will after being placed. In addition, the square desktop supported by four feet is also very practical and beautiful. But the tripod used to fix the camera is different. Photographers often have to take pictures outdoors. At this time, the ground is generally uneven, so you can only choose a tripod first.
