Photography: What are shutters and shutter applications?

Shutter is the mechanism used by camera to control the effective exposure time of photosensitive film. It is an important part of the camera, and its structure, form and function are important factors to measure the grade of the camera. Generally speaking, the larger the shutter time range, the better. Low seconds is suitable for shooting moving objects, so a camera emphasizes that the shutter can reach116000 seconds at the earliest, which can easily capture fast moving targets. However, when shooting traffic at night, the shutter time will be lengthened, and the silky water flow effect in ordinary photos can only be photographed with a slow shutter.

Application:

1, high-speed shutter captures athletes.

If you want to capture a moving image, you must set the shutter speed higher, which is enough to freeze the motion of the image. Generally, you can use a longer lens with a high-speed shutter, such as 1/500 seconds.

11000 seconds and so on. In addition to composing with a long lens, remember to set the camera shooting mode to S, that is, the shutter priority mode, set the high-speed shutter speed, let the camera automatically adjust the appropriate aperture for you, concentrate on composing, and set the continuous shooting if necessary.

2. The low-speed shutter displays the dynamics.

If you want to shoot flowing water like cotton candy or flowing water like clouds, you should use the characteristics of the shutter. The reason why running water becomes this feeling is mainly to blur the image with a slow shutter. For such works, the shutter speed can be set at115 or 1/8 seconds or even as long as 1/2 seconds, and the shooting mode is M mode or S mode. Because the shutter speed is very slow, you must cooperate with a tripod to stabilize the fuselage.

3, B shutter to shoot fireworks

The so-called B shutter is that the photographer controls the shutter time himself, which is the most convenient for shooting fireworks. When shooting, just fix the camera on the tripod, connect the cable releaser, set the camera to M mode, set the aperture around F8, and set the shutter to "B". Press the shutter when you see that the smoke is hot. When the fireworks unfold to a certain extent, leave the shutter and let it close.
