What is the role of the shutter in photography?
The main function of the camera shutter is to control the length of exposure time. Different exposure times will produce different results.
When shooting, we can control the shutter speed to capture different picture effects, such as: using a high-speed shutter to freeze fast-moving objects, using a slow shutter to capture light trails, etc.
The unit of shutter speed is "second". Common shutter speeds are: 4 seconds, 2 seconds, 1 second, 1/2 second, 1/4 second, 1/8 second, 1/15 second, 1/30 second, 1/60 second, 1/125 second, 1/250 second, 1/500 second, …………. The larger the denominator, the faster the shutter speed and the shorter the exposure time; the smaller the denominator, the slower the shutter speed and the longer the exposure time.
Generally speaking, 1/2 second and 1/4 second are very slow speeds; 1/30 second and 1/60 second are slow doors; 1/250 second and 1/500 second are High-speed shutter; if the shutter speed reaches 1/2000 second or 1/4000 second, it is a very fast shutter speed.
The following table lists the shutter speeds for common shooting themes:
4. Use shutter priority to shoot
Shutter priority means that when shooting, you You can manually adjust the shutter speed, and then the camera will calculate a reasonable aperture value based on the shutter speed you set and the light in the environment when shooting, thus completing the entire exposure process.
Using shutter priority mode to shoot can record the trajectory of moving objects very well, so shutter priority mode is suitable for shooting sports subjects, such as: sports photography, racing, animals, etc.
