Digital camera

Definition

A digital camera is an electronic device that captures and stores images in a digital format, allowing for immediate viewing, editing, and sharing. Unlike traditional film cameras, digital cameras use image sensors to convert light into electronic signals, which are then processed and stored on memory cards. This technology has transformed photography by enabling users to take countless photos without the need for film, offering versatility in settings and effects.
