What is a Digital Camera

A digital camera is a hardware device that captures and stores photographs in digital format. It uses electronic sensors to convert light into digital data, allowing users to take high-quality images without the need for film.

Unlike traditional film cameras, digital cameras do not require the use of physical film to capture images. Instead, they use memory cards or built-in storage to store digital images, making it easy to transfer and share photos electronically.

How Digital Cameras Work

When a digital camera is used to take a photo, the electronic sensor inside the camera captures the light that enters through the lens. The sensor converts this light into electrical signals, which are then processed and stored as digital data.
