What is a primary goal of using a slow shutter speed?

Using a slow shutter speed is primarily aimed at creating motion blur. This technique is particularly useful in photography when you want to convey a sense of movement or passage of time. By allowing the shutter to remain open for an extended period, moving subjects—such as flowing water, traffic, or a person running—will appear blurred in the final image, while static elements remain sharp. This contrast effectively captures the essence of motion and can add a dynamic quality to a photograph, illustrating how movement interacts with the stillness around it.

In contrast, freezing motion typically involves a fast shutter speed, which quickly captures the scene before any movement can blur it. Increasing image brightness is more often achieved through adjustments in aperture and ISO settings rather than shutter speed. Enhancing color saturation relates to post-processing techniques or specific camera settings that adjust vividness, not the shutter speed directly. Therefore, using a slow shutter speed to create motion blur is a fundamental technique for artists looking to impart energy and fluidity to their images.
