How does a camera use visible light to take a photo?

A camera captures visible light by allowing it to enter through the lens, which focuses the light onto a sensor or film. The sensor or film then records the intensity and color of the light, creating an image. When the shutter is opened, it exposes the sensor to the light for a specific duration, determining the exposure and overall brightness of the photo. This process transforms the light into a digital or chemical representation of the scene being photographed.
