A camera is a device used to capture images, either as still photographs or as moving images such as videos or movies. The technology operates on the principle of optics—the capture of light patterns, reflected or emitted from objects, onto a light-sensitive medium in a controlled manner. Traditional cameras used photographic film where chemical reactions would imprint the image, but modern cameras are predominantly digital, with images captured via an electronic image sensor. These sensors convert light into electrical signals, which are then processed into digital files that can be stored, displayed, and edited on computers. Cameras come in various forms, from the simple smartphone cameras and point-and-shoot models to complex digital single-lens reflex (DSLR) and mirrorless cameras with interchangeable lenses. They play a crucial role in numerous activities, from personal photography and filmmaking to scientific research, surveillance, and journalism, providing a powerful tool for documenting, expressing, and sharing visual perspectives.
