When trying to arrest movement with shutter speed, closer subjects require:

1. Fast speeds

2. Slow speeds

3. No shutter speed adjustment

4. Moderate speeds

The correct answer is: Fast speeds

When attempting to arrest movement with shutter speed, it is important to understand how different distances from the subject affect the required shutter speed. Closer subjects typically exhibit more pronounced motion blur if captured with slower shutter speeds compared to subjects that are farther away. This happens due to the fact that movement can cover a greater angular displacement in the frame when the subject is nearer to the camera. To effectively freeze motion of a closer subject, a fast shutter speed is necessary, as it minimizes the time the camera's sensor is exposed to the moving subject, allowing it to capture a sharp image without the blurring effect caused by motion. Fast shutter speeds are particularly useful for freezing fast-moving subjects, such as athletes in action or animals in motion, where any slight movement can lead to significant blur. In contrast, slower shutter speeds might suffice for subjects that are further away or moving gradually, as the impact of motion is less pronounced at that distance. Therefore, adjusting to a fast shutter speed is crucial for maintaining clarity and detail when photographing subjects that are close to the camera.
