Shutter speed

Shutter speed is like a magic trick that your camera does. When you take a picture, the camera opens up a little door called a shutter to let light in, and then quickly closes it again. The speed at which the door opens and closes is called the shutter speed.

Just like how you can make a silly face really fast and then go back to normal, cameras can take pictures really quickly too. Sometimes, you might want to take a picture of something that is moving really fast, like a bird flying in the sky or a car driving by. If you make the little door open and close really quickly, you can freeze the movement of the bird or car and capture a clear shot.

On the other hand, sometimes you might want to take a picture of a scene that is very dark or dimly lit. If you make the little door stay open for a longer time, more light can come in and you can get a brighter picture. But, if you hold the camera in your hand while the door is open for too long, the blur can be caused by the shaking of your hand.

So shutter speed is important because it can help you take clear pictures of fast-moving objects and capture the amount of light you want in a picture.
