Digital photography is a technological process that involves capturing and recording images using electronic sensors rather than photochemical film. The process begins when light reflected from a scene strikes a sensor array, typically composed of silicon components such as Complementary Metal-Oxide-Semiconductor (CMOS) or Charge-Coupled Device (CCD) technology. Each photosite within the sensor measures the intensity and spectrum of incident light, generating an electrical charge proportional to the light captured. This continuous stream of analog electrical data is then converted into a digital format through an Analog-to-Digital Converter (ADC). The resulting data structure, which includes pixel values for color and brightness, is compressed and stored digitally, allowing for immediate viewing, editing, and preservation of the image.
