camera

A camera is a device that captures images, either still or moving, using light. It works by allowing light to enter through a lens, which focuses the light onto a sensor (in digital cameras) or film (in traditional cameras). This process creates a photograph or video. Cameras come in various forms, from smartphones to professional equipment, and can be used in numerous settings, such as for personal memories, artistic expression, or professional work. Key components include the lens, shutter, and viewfinder, each playing a role in how the final image is produced.
