Which setting is suggested to achieve a little to a lot of blur for action photos?

To achieve a little to a lot of blur for action photos, using a slower shutter speed is effective. A slower shutter speed allows the camera to remain open for a longer duration, which can capture the movement of a subject across the frame. This technique is particularly useful for conveying a sense of motion, adding a dynamic quality to the image.

By controlling the amount of time the sensor is exposed to light while the subject is moving, photographers can create varying degrees of blur that either subtly hints at motion or dramatically emphasizes it. For example, a slight blur can indicate movement while still maintaining some detail, whereas a more pronounced blur can create a more abstract feel or showcase rapid movement.

In contrast, faster shutter speeds freeze motion, capturing details crisply and sharply, which contradicts the goal of introducing blur. The options mentioning "inversely proportional" and "freeze motion" do not apply directly to the desired outcome of achieving blur for action photos. Therefore, selecting a slower shutter speed is the correct approach when aiming to depict motion through blur in photography.
