A camera is a device used to capture images, either as still photographs or as moving images such as videos. It works by allowing light to enter through a lens and onto a sensor or film, which records the image. Cameras come in various forms, from simple point-and-shoot models to complex digital single-lens reflex (DSLR) cameras, each designed for different levels of photography expertise. In recent years, the evolution of camera technology has led to the rise of smartphones equipped with high-quality cameras, making photography accessible to everyone. Whether for professional use or casual snapshots, cameras play a crucial role in documenting moments and expressing creativity.
