In digital photography, integrated circuits, which are sensitive to light, recordimages as a grid of pixels rather than using the silver and light-sensitive dyes thatfilm use. These integrated circuits are called CMOS (complementary metal oxide semiconductor)sensors or CCDs (charge-coupled devices). These circuits are the backbone ofdigital cameras. In other words, everything revolves around these "chips," whichrecord light and then translate them into ones and zeros.When a CCD is charged with electricity, the sensors in the CCD become sensitive tolight. The CCD chip is made up of millions of sensors that can record light similar toconventional film.
