True or False: A faster shutter speed lets in less light.

A faster shutter speed indeed allows less light to reach the camera sensor. The shutter speed controls the duration for which the camera’s shutter remains open, determining how long light can enter the camera. When the shutter opens for a shorter period—characteristic of a faster shutter speed—fewer photons of light can enter compared to a slower shutter speed, which stays open longer and permits more light.

In terms of photographic practice, using a faster shutter speed is advantageous in situations where motion must be frozen, such as in action shots. While this speed allows for clarity and detail in fast-moving subjects, it also necessitates compensatory adjustments in other settings, like aperture or ISO, to achieve a well-exposed image in varying lighting conditions.
