How it's used
Refers specifically to the mechanical or electronic mechanism that controls exposure duration. While it is a technical term, it is frequently used by hobbyist photographers in casual conversation when discussing settings or equipment performance. It is distinct from the aperture, which controls the size of the opening rather than the duration of the light exposure.

Common mistake
Beginners sometimes confuse the shutter button, which is the physical button you press to take a photo, with the shutter mechanism itself. In Cantonese, you might use 撳快門 to refer to the action of pressing the shutter button, but the term 快門 technically refers to the internal component.
