Photography knowledge: what is a slow door?

Slow door refers to adjusting the shutter speed of the camera to1/30s-1/60s.

Slow door speed refers to slow shutter shooting, which can not only adapt to the lack of light, but also capture more powerful pictures in some scenes.

It is a method of using a slow shutter for a fixed camera, which can often capture the audience clearly, and the line that the athlete ran can be virtually pasted as a trace. The technical requirements of this method are relatively low; Using a slow shutter and moving the camera at the same time is a more technical shooting technique, which we usually call "shaking" or "chasing".

1, slow down the shutter speed.

Set the shutter speed to be slower than the standard speed, but not too slow, which will make it difficult to shoot a clear object. For example, if you follow a car, you can adjust it to 1/60 per second and keep shooting until you get the best picture. When the photographer walks or cries, it can be adjusted to 1/30 per second. The faster the shutter speed, the clearer the background and the less blur caused by motion.

2, autofocus

Start the autofocus function, press the shutter half-way, and lock the moving target. After pressing the shutter completely, you should continue to follow the shooting, so as to create smooth blurred lines from beginning to end. If the camera shutter speed is not enough, you can focus in advance to ensure that the subject is always in the picture.

3. Choose the best shooting point

It is very important to choose the right location if you want to take a good photo. This place must be safe and clear. You can also use a telephoto lens to keep a certain shooting distance.

4, keep the same level with the main body.

Put the camera in the horizontal position of the subject, which will help you focus better and take a clear picture of the subject.

5. Leave enough space for the theme Another important skill is to leave enough space between you and your theme. Insufficient space will limit your tracking.
