A digital camera takes light and focuses it via the lens onto a sensor made out of silicon. It is made up of a grid of tiny photosites that are sensitive to light. Each photosite is usually called a pixel, a contraction of “picture element”. There are millions of these individual pixels in the sensor of a DSLR camera.
How does a digital camera capture an image?
Unlike a conventional camera that captures images on film, a digital camera uses tiny light-sensitive diodes which convert light into electrical charges. The image is recorded as squares or “pixels.” A digital photograph is made up of millions of these pixels.
How a camera works step by step?
A camera lens takes all the light rays bouncing around and uses glass to redirect them to a single point, creating a sharp image. When all of those light rays meet back together on a digital camera sensor or a piece of film, they create a sharp image.
What type device is a digital camera?

How do analog cameras work?
Analog cameras capture images by exposing photographic film to light, with the scene in front of the lens being reproduced onto the material thanks to the chemical reaction between the silver halides and the light itself. The film is then developed in a darkroom and turned into an actual photographic print.
How does a DSLR camera work?
A DSLR camera works by use of a reflex mirror (or prism) that reflects light into the optical viewfinder, allowing the photographer to capture the image they’re seeing in front of them. Light passes through the lens and is reflected off a mirror or prism inside the camera body.
