What is the purpose of shutter speed?

• A. To enhance color saturation in images
• B. To determine the duration the sensor is exposed to light
• C. To adjust the focal length of the lens
• D. To set the level of digital noise in the image

Answer: (B)

The purpose of shutter speed is to determine the duration the camera's sensor is exposed to light. This duration is crucial because it affects the overall exposure of the image, influencing how light or dark the photograph appears. A fast shutter speed allows for a brief exposure, which can freeze motion and help capture sharp images of moving subjects. Conversely, a slow shutter speed increases exposure time, allowing more light to hit the sensor, which can enhance the visibility of darker scenes or create motion blur, conveying a sense of movement. Understanding shutter speed is essential for photographers, as it directly impacts the visual quality of their images and allows them to creatively manipulate how motion is captured. The other options refer to different aspects of photography, such as color saturation, focal length, or digital noise, which do not relate to the function of shutter speed in controlling light exposure.
