Dear gods, how to adjust the shutter speed?

First of all, confirm whether our subject wants to capture, record the motion trajectory or take a clear shot: to capture, we should give priority to increasing the shutter speed, record the motion trajectory and slow down the shutter speed. If we take a clear shot, we can master its safe shutter.

Secondly, to know how fast the shutter speed is adjusted and how much it is reduced, it is necessary to combine the control of photo brightness: when shooting with a high-speed shutter, try to open the aperture or improve ISO when the picture is dark, or reduce the shutter speed appropriately; When shooting with a slow door, if the picture is bright, you should consider reducing the aperture or ISO, or increasing the shutter speed.

Finally, when the novice photographer adjusts the shutter speed, it is suggested to adjust the shutter speed step by step, which is more conducive to understanding the control of shutter speed on the picture effect and brightness. After proficiency, he can reasonably adjust various exposure combinations and choose what he needs.

The faster the shutter speed, for example, when the shutter speed is 1/500 seconds, the runner can shoot very clearly; As the shutter speed slows down, people with 1/2 seconds appear the problem of blurred virtual shadow, which shows that attention should be paid to the control of shutter speed when shooting moving objects. The faster the shutter speed, the clearer the picture will be.

In the actual shooting process, we should pay attention to the safety shutter when shooting any subject, so that the shutter speed is faster than the safety shutter, which is likely to avoid the situation of virtual shadow blur. Usually, the safety shutter has such a formula:

Safety shutter = 1/ equivalent focal length. For example, for a full-frame camera, if a lens with a focal length of 50mm is used, the safest shutter speed is 1/50 seconds, and it is recommended to shoot at least 1/50 seconds when shooting.

Of course, this paper mainly discusses the difference of picture effect brought by high-speed shutter and slow door.

1, high-speed shutter-snapshot moment

A high-speed shutter generally means that the shutter speed reaches or exceeds1125 seconds, such as 1/250 seconds,11000 seconds, etc. Because the exposure time is very short, it can capture the instantaneous posture of the subject very well, so we often use it to take snapshots, such as shooting sports and the wild.

2, slow door-record the light spot trajectory

Slow shutter, which we often say, means that the shutter speed reaches or is slower than115 seconds, such as 1/2 seconds, 30 seconds, etc. Because of the long exposure time, the camera will record the moving track of the light spot in the picture, thus shooting a slow shutter work with good picture effect. For example, shooting busy car tracks, star tracks, painting atomized waterfalls, light painting, floating clouds and so on.
