What effect does a faster shutter speed have on motion?

A faster shutter speed captures images in a shorter amount of time, which significantly reduces the motion blur that can occur when subjects are moving. This is particularly advantageous in scenarios where you want to freeze action, such as in sports photography or while capturing wildlife. By minimizing the duration the shutter remains open, a fast shutter speed effectively "freezes" fast-moving subjects, allowing you to capture crisp, sharp images without the effects of blur that slower shutter speeds might introduce.

The other outcomes associated with shutter speed, such as light exposure and blur, are indeed impacted by speed, but they relate more to the consequences of using different settings rather than the primary effect of a fast shutter speed, which is to stop motion.
