Which of the following is a common feature of action photography?

In action photography, capturing the dynamic movement of subjects is a key element. Blurred backgrounds are commonly utilized to emphasize this action and create a sense of motion. This technique, known as motion blur, helps to convey speed and urgency, drawing the viewer's attention to the subject that is in motion while creating an intentional contrast with the blurred surroundings.

Using a slower shutter speed can accentuate this effect by allowing the background to blur while the main subject remains in focus, making the action feel more vibrant and alive. This is especially useful in sports and wildlife photography, where the goal is to highlight the movement and energy of the scene.

Other options, such as static subjects, deadpan expressions, and vibrant color schemes, do not contribute to the characteristic feel of action photography. While they may appear in various contexts, they do not specifically enhance the sense of movement that action photography aims to achieve.
