Movement across the angle of view, such as left to right, generally requires:

1. Slower speeds

2. Faster speeds

3. Minimum speeds

4. Average speeds

The correct answer is: Faster speeds

When capturing movement across the angle of view, such as a subject moving from left to right, faster shutter speeds are typically required to freeze the action effectively. A fast shutter speed allows less light to hit the sensor but captures images in a fraction of a second, reducing the likelihood of motion blur that can occur with slower speeds. In scenarios involving fast-moving subjects, utilizing a quick shutter speed ensures that the image is sharp and that the subject's motion is clearly defined without unwanted blurriness. This is particularly important in sports photography, wildlife photography, or any situation where subjects are dynamic. In contrast, slower speeds may introduce motion blur, which is desirable in some artistic contexts but usually not in instances where clarity is required to represent an action or movement accurately. Minimum and average speeds would not provide the quick response needed to capture fast lateral movements without blur.
