How does a camera work?

A camera is like a box that catches light and turns it into pictures.

Imagine you're playing with your favorite toy, let's say a teddy bear. When the light from the room hits your teddy bear, it makes it visible to you. A camera works in a similar way. It uses something called a lens, which is like a special window that lets light come in and focuses it.

How Light Becomes a Picture

Inside the camera, there's something called a sensor, think of it as a group of tiny detectives who catch the light coming through the lens. These detectives record how bright or dark things are and what colors they have.

When you press a button on the camera (like pressing a toy’s switch), the sensor takes all that information and stores it in something called memory, just like how your brain remembers what your teddy bear looks like after you close your eyes.

Later, when you want to see the picture, the camera uses the information from memory to show you the image on a screen or print it out as a photo. It's like drawing a picture of your teddy bear based on how it looked in the light!
