When you click the button, you instantaneously record the reflected light off objects in the camera’s field of view.

How does digital camera works?

A digital camera takes light and focuses it via the lens onto a sensor made out of silicon. It is made up of a grid of tiny photosites that are sensitive to light. Each photosite is usually called a pixel, a contraction of “picture element”. There are millions of these individual pixels in the sensor of a DSLR camera.

How does a camera work physics?

Cameras use convex lens to take real inverted images. This is because light rays always travels in a straight line, until a light ray hits a medium. The glass causes the light rays to refract (or bend) this causes them to form inverted on the opposite side of the medium.
