Digital cameras are devices that capture images using electronic sensors instead of film. They allow users to take high-quality photos and videos, which can be easily stored, edited, and shared. With features like zoom lenses and various shooting modes, digital cameras cater to both beginners and professional photographers. One of the key advantages of digital cameras is their ability to instantly review images on a screen, making it easy to delete unwanted shots. Popular brands like Canon, Nikon, and Sony offer a range of models, from compact point-and-shoot cameras to advanced DSLRs and mirrorless cameras.
