A fast shutter speed...

• A. Increases depth of field
• B. Freezes or stops the action
• C. Overexposes the image
• D. Softens details

Answer: (B)

Fast shutter speeds control how long the sensor is exposed to light. When you use a fast speed, the shutter is open for only a tiny moment, so moving subjects don’t have time to blur. That’s what it means to freeze or stop action—you capture crisp details in fast-moving scenes like sports or wildlife. Depth of field, on the other hand, is mainly determined by aperture, focal length, and distance to the subject, not how quickly you snap the photo. A fast shutter speed usually reduces exposure, so you’d need enough light, a wider aperture, or a higher ISO to avoid underexposure. And soft details come from motion blur or camera shake, which happen with slower shutter speeds, not fast ones.
