A camera 📷 is a device that captures and records visual images. It allows users to capture still photographs or record videos by focusing light onto a photosensitive surface, such as a film or an electronic sensor. Cameras come in various types and formats, including digital cameras, DSLRs (digital single-lens reflex), mirrorless cameras, and smartphone cameras. They are used for personal photography, professional photography, filmmaking, surveillance, scientific research, and many other applications.
