It collects light and focuses it onto a special surface inside the camera. Old cameras used film to record the light. Modern digital cameras use sensors. When you press the button on a camera, the light enters, and an image is captured. This image can be stored on film or as a digital file on a memory card. Cameras also have settings to control how much light enters. For example, the shutter opens and closes quickly or slowly to capture motion or stillness. The aperture is another part that controls how bright or dark the picture will be. Some cameras let you zoom in to see faraway objects. Flash is used to take pictures when it’s dark. Cameras are in phones, tablets, and even computers, making it easy to snap pictures anytime.

Paragraph on ‘How do Cameras Work?’ in 300 Words
Cameras are amazing tools that let us capture pictures and videos of the world around us. They work by using light to create images. The most important part of a camera is the lens. The lens acts like an eye, collecting and focusing light onto a special surface inside the camera. In older cameras, this surface was called film, and it needed to be developed to see the pictures. Today, most cameras are digital and use sensors instead of film. These sensors turn light into digital images you can view on a screen.
When you press the camera button, the shutter opens for a moment to let light in. The amount of light is controlled by the shutter speed and the aperture. Shutter speed can be fast for action shots or slow for low-light photos. The aperture is like a tiny window in the lens that changes size to make pictures brighter or darker.
Cameras can also zoom in to make faraway objects look closer. Many have a flash to brighten dark places. Some cameras even have special modes for portraits, landscapes, or sports.
Nowadays, cameras are found in smartphones, tablets, and computers, making it easy to take pictures anytime. They are used to capture memories, create art, or share stories. From beautiful sunsets to funny selfies, cameras help us hold onto special moments forever.
