About shutter

1, Shutter is the English name of shutter. Shutter is a device used in camera equipment to control the time when light irradiates the photosensitive element. In addition, shutter was launched by CERNET. Relying on CERNET's rich network resources, marketing and channel foundation, Shutter provides China college students with a variety of network services, such as VoIP, IM instant messaging, online film and television music, genuine software, career counseling and so on. Shutter points can be exchanged for all domestic calls, and you can call fixed landlines, mobile phones and PHS online. But at present, only the revised education network is supported. Confinement is also an American horror movie released in 2008.

2. Shutter is a mechanical device 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.

3. Speed: The shutter speed unit is "seconds". The highest shutter speed of professional 135 cameras reaches116000 seconds. Common shutter speeds are:11/21/41/811/301/65438+. The shutter speed exposure of two adjacent stages is twice different, and we often say that the difference is one stage. For example, the exposure of1/60s is twice that of1125s, that is,1125s is one step slower or one step lower.

4. Exposure mode: After we decide the shutter speed ourselves, the camera metering system will automatically select the appropriate aperture F value (which can be stepless F value) according to the light conditions at that time. Digital cameras equipped with exposure mode dial usually engrave the letter "S" on the dial, which stands for the required shutter mode. Shutter priority mode is suitable for photography that needs to control the shutter. High-speed shutter can condense action, and slow shutter can turn moving vehicles into light beams.
