Skills of slow photography

When using a slow shutter, the camera generally needs support, and it is best to use a tripod or a monopod to stabilize the camera. 1/30 seconds below all levels of shutter speed is very slow. Which level to use depends on the moving speed of the subject and the picture effect to be displayed. If the selection speed is too slow, the image is likely to be completely blurred and people can't see it clearly; The speed of choice is too fast, and the sense of movement is lost. Therefore, if you are not sure, you can use several shooting files to find the best shutter speed, which will not blur the photos, but also show a certain sense of movement.

According to the shooting method, use the slow shutter to actually shoot. It is different from the former method in that the former is a fixed camera, which allows moving objects to pass in front of the camera lens and leave moving images on the negative, while the latter is a moving camera, which moves with the movement of the moving objects. When the moving object is at the same speed as the moving camera, the moving object is relatively static, and the image left in the photo is also static, while the scenery around the moving object becomes a "moving" scene because of the motion of the camera. This kind of relative motion makes the original static scene leave a fuzzy moving image on the negative, giving people a sense of movement.

Follow-up is often used in sports photography to show the state of fierce competition. When using the follow-up method, you should choose dark scenes such as trees and crowds with a small amount of bright scenes, and it is best to use side backlight. In this way, when the mobile phone camera follows the moving body, obvious lines will appear in the background, reflecting the sense of movement. In the choice of shutter speed, generally speaking, the speed is slow and the following effect is strong, but it is not easy to master technically, so the whole picture will be blurred and there will be no clear points. Therefore, when choosing the shutter speed, we should comprehensively consider the moving direction, moving speed and following effect of the moving object. Some moving objects move very fast, so the shutter speed used should be increased accordingly. Sometimes it takes 1/60 seconds, or even more than1125 seconds. In order to make the subsequent photography successful, the photographer must press the shutter with his eyes fixed on the moving object and press the shutter while moving the camera. The camera can't stop moving because the shutter is pressed. There are many ways to follow the shooting, except oblique following, vertical following, zoom following, parallel and horizontal following and so on.
