What happens when using a slower shutter speed?

Using a slower shutter speed allows the camera’s sensor to be exposed to light for a longer duration. This extended exposure time can capture motion, which is particularly noticeable when photographing moving subjects. Instead of freezing the action, a slower shutter speed results in motion blur, which can creatively depict movement and convey a sense of speed or fluidity within the image.

This effect can be advantageous for capturing dynamic scenes, such as flowing waterfalls or moving vehicles, where the blur accentuates the motion and adds visual interest. Photographers often use slower shutter speeds intentionally to achieve specific artistic effects.

In contrast, options that suggest less light entering the camera or creating sharp focus on moving subjects do not align with the characteristics of a slower shutter speed, as these are typically associated with faster speeds that freeze motion. Additionally, stating that there is no effect on image brightness contradicts the fundamental principle that shutter speed directly influences exposure; slower shutter speeds increase exposure, thereby brightening the image.
