understand the shutter

WE choose different Shutter Speed to shoot different scenes according to their merit and the storyline.

Shutter speed controls light and motion. Slower shutter speeds let more light in, creating a lighter image. With faster shutter speeds you get less light, and a darker image. Also, the faster the shutter speed, the sharper the image will be. In contrast, the slower settings will produce more blurry photos. So, if you're taking pictures of fast moving subjects, like you would at a sporting event, you'll probably want a faster shutter speed. When in doubt you should pick a medium shutter speed, about 1/60 seconds or faster. But, in order to adjust your shutter speeds, you have to switch your camera to shutter priority or manual mode. ordinary people use it auto.
