In Shutter Priority mode, what does the operator do?

In Shutter Priority mode, the operator selects the desired shutter speed while the camera automatically adjusts the aperture to ensure the correct exposure. This mode is particularly useful for capturing motion, as it prioritizes the shutter speed setting that the photographer deems appropriate for freezing action or creating blur.

By allowing the operator to focus solely on the shutter speed, Shutter Priority mode enables the photographer to have control over how motion is represented in the image while the camera takes care of the aperture setting needed for proper exposure. This balance is crucial in situations where movement is a significant factor, such as sports or wildlife photography, where quick decisions on shutter speed can lead to better image outcomes.

In contrast, other options involve setting the aperture manually or allowing the camera to determine both settings, which are not the primary function of Shutter Priority mode.
