Cameras are devices used to capture images, either as still photographs or as moving images such as videos. They work by allowing light to enter through a lens and project an image onto a light-sensitive surface, such as film or a digital sensor. Over the years, cameras have evolved significantly, from the early pinhole cameras to modern digital models that offer advanced features and high-quality imaging. Today, there are various types of cameras available, including DSLRs, point-and-shoots, and smartphone cameras. Each type serves different needs, whether for professional photography or casual snapshots. The rise of digital technology has made photography more accessible, allowing anyone to capture and share their moments easily.
