How do digital cameras work?
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 do cameras work photons?
A digital camera uses an array of millions of tiny light cavities or “photosites” to record an image. When you press your camera’s shutter button and the exposure begins, each of these is uncovered to collect photons and store those as an electrical signal.
How do digital cameras convert light into images?
To capture light from an image in digital format, a digital camera uses a special sensor, called a CCD or CMOS sensor (Grundy). Image sensors are used in digital cameras to convert optical images into digital images (Wikipedia, Image Sensor).

How is a digital image stored?
In the digital photographic world, information is captured and stored as data not as pictures. The input device (camera) converts light to a series of 1’s and 0’s and stores it on a disk or memory card. Output devices (printers and monitors) then convert this digital information back into pictures.
