shutter

The shutter controls the exposure time of the camera. Generally, it can be considered that the shutter speed is equivalent to the exposure time of a photo.

Common shutter speeds range from 30 seconds to 1/8000 seconds. 30s、 15s、8s、4s、2s、 1s、 1/2s、 1/4s、 1/8s、 1/ 15s、 1/30s、 1/60s、 1/60s、 1/ 1/020s、 1/250s、 1

The above three pictures were all taken by a rotating fan, and the speed of the fan did not change when shooting. Shutters are 1/8s (f/5.6 ISO-800), 1/ kloc-0/5s (f/5.6 ISO-1600) and1/respectively.

Application:

1. Security shutter. When the hand-held camera has the afterimage caused by hand shake, or the photos taken by the moving car have the afterimage, it is necessary to adjust the shutter properly.

2. Shoot the instantaneous state of moving objects. Such as splashing water and moving objects. Short exposure time is required, such as11000s or 1/2000s. "Figure 3 Exposure time: 1/250 seconds" is the moment when the fan rotates.

3. Streamer effect and motion trajectory. Such as traffic, running water, fireworks, etc. These require a long exposure time. Generally, the camera should be fixed with a tripod, etc., and shot with a countdown or remote control to prevent jitter and blur. If the time is not too long, just hold hands tightly. "Figure 1 exposure time: 1/8 seconds" is the blade trajectory of the rotating fan.

When the shutter is defined manually, the photos taken may be too dark or too bright if other settings are not changed. At this time, you need to adjust the aperture and sensitivity, or choose the shutter first.

Shutter priority means that when the shutter value is defined manually, the camera automatically determines the aperture size and sensitivity according to the shutter value. Mostly used to shoot moving objects.
