What typically happens when the shutter speed is very fast?

When the shutter speed is very fast, less light enters the camera. Shutter speed refers to the amount of time that the camera's shutter is open to let light in. A fast shutter speed allows light to pass through for a shorter duration, resulting in a smaller amount of light hitting the sensor or film. This is particularly useful in bright lighting conditions or when attempting to freeze fast-moving subjects without blur.

In contrast, a slower shutter speed would allow more light to enter, which is beneficial in low-light situations but can lead to motion blur if the subject moves during that exposure time. Additionally, a fast shutter speed is generally not associated with overexposure, as it tends to limit the light intake. Thus, the correct understanding of how shutter speed influences the exposure of an image highlights why less light enters when the shutter speed is very fast.
