A digital image is a photograph, artwork, or graphic created and stored as a grid of tiny elements called pixels. Each pixel contains information about colour and brightness, and together they form the complete image that can be displayed on screens, printed, or edited digitally.
Digital images are the foundation of modern photography, allowing for easy manipulation, sharing, and storage without the need for film. They can be captured by digital cameras, scanned from traditional photographs, or created entirely on computers using graphic software. Understanding pixels, resolution, and file formats is essential for photographers and designers to ensure high-quality results across different media.
