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.
