A photo scanner is a device designed to convert physical photographs into digital images. It uses light sensors to capture the details of a photo, creating a high-resolution digital copy that can be stored on a computer or shared online. This process allows users to preserve memories and organize their photo collections more efficiently. Many modern photo scanners come with features like automatic cropping, color correction, and the ability to scan multiple photos at once. Some models even include software that helps enhance the scanned images or organize them into albums, making it easier for users to manage their digital collections.
