Digital cameras are electronic devices designed to capture and store still images or videos in digital format. They have revolutionized photography, replacing traditional film cameras with their ability to record images as digital data. Digital cameras use image sensors, typically CCD (charge-coupled device) or CMOS (complementary metal-oxide-semiconductor), to convert light into electrical signals. These signals are then processed by the camera's internal electronics to create high-quality images.
Digital cameras offer various features, including adjustable settings for exposure, focus, white balance, and more, allowing photographers to have greater control over their shots. They store images on memory cards, making it easy to transfer and share photos digitally. Many digital cameras also offer advanced capabilities such as interchangeable lenses, optical zoom, and image stabilization, catering to both amateur and professional photographers. With the advent of smartphones, many people now carry a digital camera in their pockets, further democratizing photography and enabling instant sharing of moments captured in digital form.
