"shutter speed"的定义和意义

What is "shutter speed"?

Shutter speed is the amount of time the camera’s shutter remains open to allow light to reach the sensor or film. It controls the duration of the exposure and affects how motion is captured in a photograph. Faster shutter speeds freeze motion and reduce blur, while slower speeds allow more light in, creating motion blur and capturing movement over time. Adjusting shutter speed is crucial for achieving the desired effect, whether it is a sharp image or a dynamic, blurred effect.
