To effectively capture fast-moving subjects, you should opt for:

1. Slow shutter speeds

2. Average shutter speeds

3. Fast shutter speeds

4. Variable shutter speeds

The correct answer is: Fast shutter speeds

To effectively capture fast-moving subjects, utilizing fast shutter speeds is essential. Fast shutter speeds allow the camera to take an exposure in a shorter amount of time, which minimizes the motion blur that occurs when the subject is moving quickly. This technique freezes the action, making dynamic moments — such as a sprinting athlete or a bird in flight — appear sharp and detailed in the final image. In contrast, slow shutter speeds would result in motion blur, as the camera captures movement over a longer duration; this is not ideal for fast action. Average shutter speeds may not adequately address the rapid movement since they can still allow some blur to occur. Variable shutter speeds, while they offer flexibility, are less reliable for consistently freezing fast motion unless set specifically to be fast. Therefore, fast shutter speeds are the most effective choice for this type of photography.
