What does the photographic shutter mean?

Shutter refers to a component of a camera, which is used to control the time and length of light entering the camera. Press the shutter, and the camera will open the shutter and expose it. Shutter speed determines the length of time for light to enter the camera photosensitive element. The shutter controls the exposure time, which in turn controls the brightness of the photo.

In addition to exposure time, there is also an important parameter called mechanical shutter speed. Mechanical shutter speed refers to the time interval between shutter opening and closing. Generally speaking, the slower the shutter speed, the longer the exposure time of the photo, which means that the photo will become brighter. At the same time, the mechanical shutter speed also determines whether the photo can successfully freeze the moving object. If you want to shoot dynamic objects, you need to choose a faster shutter speed.

Shutters are also often used to create artistic effects. Long exposure can produce unique light and shadow effects. When shooting city lights at night, you can manually move the camera slowly to create a similar picture jitter effect. When shooting a moving object, you can use the focus-chasing shutter technology, so that even if the object moves quickly, it can accurately display its motion trajectory in the photo. In a word, shutter is an important photographic element in operation skills, and it can take a variety of photo effects when used properly.
