Digital photography does not use film to turn optical signals into electrical signals.

Digital photography does not use film, but uses CCD element of charge coupler to sense light and convert optical signal into electrical signal.

Digital photography represented by digital camera is a digital image photography tool. Its appearance is similar to that of a traditional camera, but it uses a charge coupled device (CCD) to sense light, convert the light signal into an electrical signal, and then record it on a memory card after analog-to-digital conversion. The memory card can be reused.
