What's the difference between time-lapse photography and video snapshot? What are the advantages of time-lapse photography?

Time-lapse photography can indeed be replaced by fast-forward video in many cases, and the effect is exactly the same.

But more than that, in fact, the difference between the two existed from the moment the shooting technology was invented:

The value of time-lapse photography is embodied in mobile phone photography.

When the machine position is not fixed, it is also a delay effect. It's much easier to shoot frame by frame than to shoot video honestly, and the cost is low. When the scene needs to be moved and the main body is a specific object (such as Tiananmen Square), the angle of each specific position needs to be corrected to make the composition constant, so that the picture can be continuous. Due to the lack of resources at hand, pictures are attached. )

For example, the moving time-lapse photography of Tiananmen Square needs to take two shots for each brick, and the position of each shot has changed. To put grandpa Mao's portrait in the center, you have to shake the tripod head. This is the general composition. There are about 800 bricks in front of Tiananmen Square. I took more than 1600 photos, each of which needs to be re-composed. Because the shooting time is at night, it will not be greatly affected by time; Because the operation is simple, one person can do it. That sounds really troublesome. But this is the way to lose silk.

Then if it is video shooting, it is necessary to set a track, and only in this way can the jitter of moving be reduced. The track is about 100 yuan a meter, and the vehicle will be bought separately. You probably need to buy a 4-meter appearance and connect it slowly. There are at least three photographers, one sitting in the car shaking the pan/tilt, one dismantling the track, and one holding hands at any time ... If a person finishes shooting, the first thing to consider is time, only shooting at night, which will not be affected by the change of the sky.

If you need to move to shoot the sunrise and sunset, such as the sunset in Tiananmen Square, and always take the sun as a part of the composition, then it is difficult to control the moving speed of people on the track, and it takes a lot of skill to shake the pan/tilt ... Anyway, when I think of the scene, I feel that it is not the work of people. Why not shoot one by one!

For another example, shooting the sunrise and sunset around a pavilion requires another rotating device to ensure that the pavilion is in the center, and then the background is the sunrise and sunset. If it is time-lapse photography, as long as one person goes to the pavilion and takes pictures while composing.

Advantages of time-lapse photography: Time-lapse photography has a unique continuous sexy picture, but it makes the obviously discontinuous picture look continuous, just like the common gif in video production. At the same time, the material of time-lapse photography is photos, so the requirements for shooting are more relaxed, giving you more time to compose, think, press the shutter and adjust than video.
