Leaf shutter

A leaf shutter is like a pair of doors that opens and closes very quickly to let light into a camera. The doors are called blades and they move together to control how much light enters the camera. When you press the button to take a picture, the blades quickly open and close to capture the picture. It's kind of like peek-a-boo where you cover your eyes and then quickly open them. The difference is that instead of your eyes, the camera lens is looking at the world and capturing the image for you to keep forever. The leaf shutter is important because it helps you control the amount of light that enters the camera, which can affect how bright or dark your picture looks. It also helps create interesting effects like blurring or freezing motion.
