What happens when you use a high shutter speed?

Using a high shutter speed means that the shutter of the camera opens and closes quickly, which results in a shorter exposure time. This allows for the capture of fast-moving subjects without blur, making high shutter speeds ideal for action photography or scenes where motion clarity is important. A quick shutter speed freezes the moment, providing a crisp, detailed image of fast-moving subjects like athletes, vehicles, or wildlife.

Longer exposure times, as mentioned in the first choice, would occur with slower shutter speeds, which allows more light to hit the sensor but captures movement as blur. The third option regarding reduced image sensitivity isn't directly influenced by shutter speed; image sensitivity primarily relates to ISO settings. The fourth option suggests increased light entry, which is more characteristic of slow shutter speeds rather than high ones, as faster speeds often limit the amount of light captured.
